3.0.4: Bug fixes and variable naming

This releases fixes two bugs with complex syntax and complex number notations.

Additionally I added the possibility for variable to contain a legible name for better source code editing.
An example of such a variable name would be: "$local1_isSaved"
The previous variable naming syntax has to be kept intact and is only to be expanded upon.

Features:

• Added: Post naming of variable names
• Improved: Script files now get compressed (compilation may take longer due to compression)

Bugs:

• Fixed: Exponential floating point number notations (4E-07f) now lex correctly
• Fixed: Array indexers can now properly be postfixed ($global98[$object3]++)
• Fixed: Compressing empty sections with Huffman compression doesn't throw exceptions anymore
