	* configure.in: raise version number

	* src/complil.c: compile symbolic_id and id for function nodes and
	  symbolic_id for global functions.

	* src/lexer.l, src/calc.c, src/eval.[ch], src/parse.y: SYNTAX CHANGE:
	  there is now an elt by elt addition and subtraction (.+ and .-)
	  which act like the old +,- when adding scalar to a matrix.  The +,-
	  now interpret A+x as A+x*I if A is a square matrix, and elt by elt
	  if A is a vector (row or column), else they error out.

	* src/funclib.c: the PolyToFunction now does 1 instead of x^0, since
	  this now works correctly for matrices.

	* src/lexer.l, src/calc.c, src/parse.y: make evalstack into
	  gel_parsestack since the naming was totally off

	* src/dict.h: on decompilation errors don't assert crash, just give
	  null as the function body.

	* src/geniustests.txt: add some tests and fix some old ones with
	  respect to the above syntax change.
