Alpha 4 - added the option to export tile as multiple textures

Choose export as multiple textures - then in the dialog you can choose between exporting a texture per subtile or per frame. The filenames are generated automatically by the pattern (currently not changeable). The preview shows how the texture is split and displays each subtile bitmask or frame index if you export as frames.

Changelog:

• Export as texture per subtile
• Export as texture per frame
• Fix UI buttons not working (AddTexture, ManageRulesets, ManageTemplates)
• Fix UI, frames not redrawing after ruleset change
