ZLE v.1.4.4

The drag and drop update - 1.4.4

• Added drag and drop functionality for Windows - copying files to the working directory
• New file format: .led "Level editor data" - for level data that is only important to ZLE itself such as particle system events and some options specific to the level
• Changed how Squared generation works - removed parallel processing option - all devices have the "parallel processing" speed now
• New option in settings - "Export as json" - designed for backwards compatibility, saves level in a human readable format that can be imported in future versions of ZLE
• Added multithreading to Squared - when converting multiple images, you can now select to use up to 8 CPU cores and process 8 images at once
• This feature can increase speed quite a lot but is more useful in situations where CPU has multiple cores and single core performance is the bottleneck
• Added documentation to Level.h
• Generally optimized Squared generation by 10%
• Added a Render button to the main scene window - allowes you to render a part of the level to a texture
• Textures for tilemaps can now be 2d! - tiles can be below one another
• Added "use both colors" - editor only - parameter to particles
• Added "delete" button when viewing properties of a file
• Added "new folder" button to files
• Fixed a bug with "save shader as image" 
• Slightly optimized tilemaps updating
• Slightly increased icon size of move and scale on both axis
• Fixed object selection collision detection being a few pixels off
• Fixed undo redo bug in tilemaps
• Fixed crash when closing editor and refreshing files
• Fixed drag and drop texture to sprite bug
