[localfunction] removed obsolete header
[autotools] added HAVE_DUNE_STUFF
[autotools] added recursive lib building
This should allow for .ccs with same name
in different dirs.
current state
[cmake] update BEGIN_TESTCASES to allow linking extra libs
[cmake] compile new sauce files
fix "create" defining a new function
uncomment missing expl. templ. instantiations
hint for for missing definitions
[functions.interfaces] select {Jacobian,}RangeType
[functions.interfaces] remove obsolete default argument
move type selection to inner class
Revert "[functions.interfaces] remove obsolete default argument"

This reverts commit e0d779efaf6230ad138e536672e0ed70b4c91c5a.
Merge branch 'libdunestuff-functions-problem' of http://users.dune-project.org/repositories/projects/dune-stuff into libdunestuff-functions-problem
[functions.interface] change JacobianRangeType
* Set it to double for matrix valued functions.
  This has to be changed once someone encounters
  matrix vlaued basis functions...
[functions.interfaces] instantiate all combinations
macro table for expl. instantiations
[functions.interfaces] extended generator macros
* a bit of white space, so my had will wrap around
  this more easily
* added possibility to iterate DomainFieldType and
  RangeFieldType separately
[functions.interfaces] added RangeFieldtType = long double
[functions.interfaces] reordered generator macros
* renamed them once again
* expand dimDomain first, this should allow for grids
  which do not implement all dimensions (like alugrid)
