The Squared² update [Part 1] - 1.4.1

What changed?

• Merged Squared² system with the editor - this system is now available to everyone! Squared² can be used to either convert an image or multiple frames into any white-transparent texture you'd like. The default texture is a square but it can be changed to a circle, or anything else.
• From my testing, it works best (fastest) with Nvidia GPUs with parallel processing features enabled
• Added Linux 64-bit support
• All of the main assets have been merged into the main executable on Windows (literally missing files crashing the program isn't a thing anymore)
• Context-aware shortcuts (disabling shortcuts in cases where you rename things or similar)
• Fixed a bug that completely crashes any shader functionality
• Added the changelog button
• Added checking if the level changed in any way - to remove the "Do you want to save the project?" prompt even if nothing changed between now and the last save
• Levels are using maps instead of unordered maps for consistency reasons
• 256 max character string limit is removed
• Switched to SFML 2.6.1
