after configure)
- Make CMake module installation path configurable
- Detect CMAKE_MODULE_PATH automatically
  + First call find_package(dune-common) to query its CMAKE_MODULE_PATH
  + Then setup the module path
  + After each find_package of dune module update the CMAK_MODULE_PATH
  + each module exports ist own <package-name>_MODULE_PATH in the
  + package configuration files
- Adapted dunecontrol and duneproject accordingly.

Added new CMake test for integral_constant.


[[Imported from SVN: r6993]]

C++11 requires a cast operator from integral_constant< T, v > to T. As far as I
could make out, no gcc version provides this cast in <tr1/type_traits> and only
gcc >= 4.6 provides it in <type_traits>. Therefore, the configure check now tests
for the cast operator only in <type_traits>.

Note: Our drop-in replacement conforms to the standard in the above-mentioned
sense.

- Removed dependency on cmake version 2.8.9
  Object libraries can now be created with dune_add_library(<target>
  OBJECT <sources>). It will create a GLOBAL property
  _DUNE_TARGET_OBJECTS:<target>_ that records the full path to the
  source files. Theses can later be referenced by providing
  _DUNE_TARGET_OBJECTS:<target>_ as one of the sources to dune_add_library

Try -std=c++11 before -std=c++0x as the latter causes a warning for
Clang. (solves partly FS#989)

[[Imported from SVN: r6986]]

Updated version test to gcc >= 4.1.
Added version test for clang >= 3.0.
Unfortunately I am not aware of the minimum required version of icc,
this test remains for icc >= 7.0.
White space adjustments.

Removed ifclauses around second search as due to caching the search
