tries to find an installed module via pkg-config. If pkg-config finds
an installed module, dunecontrol proceeds, although the module is
dropped from the internal tree, as installed modules don't need to be
built. If pkg-config does not find the module, an error is throughn.
If a dune.module file is found, installed versions of the module are
ignored.

The variable contains a colon seperated list of directories where
dunecontrol searchs recursively for dune.module files.

You can specify the variable
i.e.

export DUNE_CONTROL_PATH=~/AllMyFancyDuneProjects:~/DirectoryContainingTheDuneModules

dunecontrol will now search for dune.module files in ~/AllMyFancyDuneProjects and
~/DirectoryContainingTheDuneModules

  dunecontrol now supports names like 'dune-grid'.
  Note that _only_ dunecontrol supports these names. configure still lacks
  support for this feature.

Made a lib of the module search funcionality. This now used in the duneproject script to let the user decide which modules this project is to depend on.
