* src/calc.c, src/compil.c: Correctly compile/decompile all the new
	  function attributes

	* src/calc.c: correctly print out the local stuff, handle local node
	  correctly when outside of functions

	* src/funclib.c, src/graphing.c: handle eof errors from parsing
	  things correctly without dying.

	* src/dict.c, src/eval.c, src/structs.h: is_local generally should
	  not be moved around with the function.  Also correctly copy/free
	  all the other attributes when needed as well.

	* src/eval.c: Set arguments BEFORE extradict.  This should never
	  be an issue, but it feels more correct.

	* src/dict.c: when the subst list becomes empty, remove from subst
	  list to avoid unnecessary lookups

	* lib/*/*.gel: update and fix for the [] operator

	* src/geniustests.txt: Add some testcases

	* src/symbolic.c: just a comment change
