Bumped version for release

Fixes and fine tuning around the parser

This release was a long time coming. There are a lot of bug fixes around the parser and fine-tuning to provide the same functionality as the eval did but more secure.

Some bug fixes applied

Fixed the Parser hanging on a character it didn't recognize.
Fixed bug that arrays couldn't be deleted using delete.

Eval Free

This version has no eval usage in it. Eval has been replaced with a custom Parser which should work the same way most of the time.

However, there might be some problems with edge cases. Please report them as encountered.

Fixed Floating point in eval cases
