Version 1.3 released

SukiGD is now at version 1.3. This is a major release, and will require you to make a few changes to your scripts.

Changelog:

• Added window show/hide statements
• Added play keyword for custom animations
• Added Skip/Auto modes
• Refactored the dialogue system to use a fetch cycle
• Refactored the display function to allow for text speed/rolling display
• Added a centered keyword to display text at the center of the screen. This uses its own font resource
• Improved error handling in the compiler. It should be more readable now
• Removed the constants files entirely. The interpreter now uses direct references to node names
• Miscellaneous tweaks

If you find any bugs, please let me know and I'll fix them ASAP. The next major feature planned is the ability to save and load state dictionaries.
