Eva cleanup
Merge pull request #143 from Cazra/master

Some more gui clean-up.
Updates to the documentation.  Still much more to do, but have started the rules and strategies section.
Added is_constant to Core.eli.
Added integer math operations, and renamed some operations to start with an i for integer.
Corrected bug in declaring rules that require completion.  The issue was a problem with handling #ruleset versus #rulesets when interpreting the content of a SpecialFormHolder to create the RewriteRule.

Updated documentation and fixed bug in rule completion.
Updated build to compute the full version and use it in the Scaladoc.  Updated TreeSprite to correct a bad Scaladoc comment.
Adding start of profiler, and start of new parser (which is currenlty broken).
More work on new parser.
Parser nearing completion.  Only remaining item is numbers, and then testing.
Finished the new parser, and integrated it with the rest of Elision.  It is now possible to select the parser at startup (via -p) and to suppress bootstrapping (via -N).  The parser can also be selected with set_parser from inside Elision.
