IteratorRanges are convenient for storing ranges of iterators into a
larger container, e.g. for the per-codim GeometryTypes in an
IndexSet. Unfortunately, you can't just create an array of
IteratorRanges right now because they can neither be copied, nor are
they default-constructible.

This patch fixes that problem and also adds a second typedef
const_iterator to make IteratorRange work in contexts where the
iterating code isn't using range-based for and assumes a const object.

Setting a policy must be guarded as older CMake version do not
know about the policy.

CMake >= 2.8.12 can optionally use @rpath to embed dynamic linker paths
into shared libraries on OS X. This greatly improves reliability with
libraries in non-standard locations and should definitely be turned on
by default.

The shell script logic for switching dune_enable_all_packages() on or
off in duneproject was broken and always turned the feature on, ignoring
the user input.

Fixed by testing for the actual contents of the variable instead of its
length and by converting the contents to lowercase before.

The storage of bigunsignedint was changed to std::uint16_t in commit
541b3dfc. This implements the same
change for the MPITraits<bigunsignedint<k>>

Note that this assumes that
  MPITraits<std::uint16_t>
is defined. This is the case as long as uint16_t maps to one of the
standard integer types (unsigned char/short/int/long).

Thanks to Markus for pointing this out.

The duncontrol / dune.module mechanism allowes to overload the run_* commands, which
are executed in order to setup/build/etc. a module. This patch fixes a bug in the cmake
parsing of the dune.module file. Somehow cmake tried to interpret the content of the
dune.module as cmake code. We now use a different strategy to parse the file and avoid
storing the content in a temporary variable.

script. This feature is disabled by default and can be enabled by
-DALLOW_CXXFLAGS_OVERWRITE=ON.

This branch fixes a number of problems related to
dune_enable_all_packages():

- The feature requires at least CMake 2.8.12, which is more recent than
  the baseline requirement of the core modules (2.8.12). We now check
  for that when executing the relevant functions and also remind the
  user to set the correct version in cmake_minimum_required().
- Updated the documentation to also state the version requirement.
- The duneproject script now also warns the user about the more
  stringent CMake version requirements when using the feature and sets
  the correct minimum required CMake version in the new module's main
  CMakeLists.txt file.
- There was a bug in duneproject that caused it to always enable
  dune_enable_all_packages(), ignoring the choice made by the user. That
  bug is fixed in this branch.
- Some minor fixes to duneproject while I was at it.

This fixes FS1678.

* feature/FS1678:
  [dunecontrol] Output choice of external package handling and required CMake version
  [duneproject] Allow specifying ENABLE_ALL as 5th command line argument
  [duneproject] Update CMake minimum version if ENABLE_ALL is true
  [duneproject][Bugfix] Make sure dune_enable_all_packages() can actually be disabled
  [CMake] Improve documentation in DuneEnableAllPackages.cmake
  [CMake][Doc] Add required CMake version to dune_enable_all_packages()
  [CMake] Require CMake 2.8.12 for dune_enable_all_packages()
  [CMake] Fix typo in warning message.
  Add a warning that some functions are 2.8.12

For discussion check FS1648.

Disabling a cmake module through CMAKE_DISABLE_FIND_PACKAGE_...
was only partially working:
- Any module suggesting the disabled module would not search for it
- dunecontrol did not have this knowledge and built the disabled module nevertheless

This commit fixes the latter.

the first problem was that I accidentially enabled the ScalarOrderingTest, but this forced me
to investigate further and I found out how this works, or not works.

We have to add the comparison operators to FieldVector, as the cast operator does not always
match, e.g. in the case of GMPField.

The templated constructor of GMPField fatched everything. We reduce the constructor
to those scalar values, which are convertible to mpf_class. As this removes the constructor
from char* we explicitly add constructor from char* and std::string.

most of the tests work. std::complex<GMPField> does not work as expected, but this is
perhaps something we don't want to support. As std::complex does not allow to initialize
with other parameters than the data type itself, we can not initialize from int or other
compatible scalar values. The smae problem occures when interacting with int values directly.
