The latter really doesn't make much sense.  The implementation
always returns 'true' now.  That doesn't really make me happy,
though.

Also tried to implement local() for the same class.  I used
UG_GlobalToLocalBnd(), but that doesn't really hold up to its
promises, so the implementation is outcommented.

  (is not specific for P1 elements any more)
- reworked template parameters such that the P1Operator does not need
  to know the local assembler type
- assemble method now gets a reference to the base class, so you
  are forced to use it.
