WIP: Another major refactor, rewriting the CSS parser to be more robust
and not rely on regexes as heavily.

'jvStdLib' renamed to 'jvCoreLib'
'jsStdLib' renamed to 'core'
JavaScript in the RSM file is now run BEFORE the GUI loads. Code that
must run after the UI loads should be placed inside of the function
program.onload() {}

THIS IS NOT FULLY FUNCTIONAL OR TESTED. CSS STYLING IS DISABLED.
Meaningful error logs that actually tell you what file caused the
problem.

STILL WIP COMMIT
Almost got basic styles working, removed CSSParser class as it is no
longer needed.
