Added int() and len() to the standard library.
int() converts a value to an integer primitive.
len() returns the element count of an array or dictionary reference.
Implemented HashTables for Dictionary types.
Unionized VALUE types to reduce memory usage.
Re-implemented dictionaries with HashTable().
Changed hashing function for strings
Removed error checking parse tree results.
This was really unnecessary code, removing conditional clauses added about 5% to the interpreter's performance.
