Log Message:
-----------
* fixed a serious bug in vector.h: dangling references to vectors could
  be stored in expression objects when nested vectors are used.
  This happend because some functions (eval, null_expr stuff and
  meta_vector::sum/prod) took a const& vector and returned the same vector
  as value. A referene to this temporary was then stored in the expression
  object instead of the real vector
* added a debugging mode to vector.h which traces if any dangling
  references are used when evaluating an expression. This mode is
  enabled in the unit test and disabled in the game (since it
  changes memory layout of the vectors and breaks usage in OpenGL
  vertex arrays)
* added an option in CMakeList.txt to disable inlining (gcc only)
