Ver 1.3.0 - Performance Optimization and adjustments

This update brings performance optimization and also:

• Walk Idle Run now works with standard RPG Maker spritesheet (3 frames, $filename.png)
• All extended frame spritesheet ($filename_fx.png) now all start with the first frame but are also not forced to stay on it if the character starts moving.

Highly recommended to update to this ver, mostly for optimization as it's less CPU heavy.
