Crisp visuals + bug fixes and stability improvements

This update features crisper shape drawing across the board.

Browsers default to scaling down the canvas texture size to preserve a similar physical drawing size for shapes regardless of the device. This has the side effect of making the canvas appear blurry. This is now fixed, so that whenever you draw something in Codetoy it will draw at full resolution even on high DPI devices.

This update also addresses a host of stability problems, bug fixes, and QOL improvements.

• Fix bug with C# runtime failing to run
• Renamed "Projects" page to "My Projects" for better clarity
• "My Projects" button in codetoy editor now takes you to your projects page instead of the explore page
• Fixed stroke() function setting fillStyle instead of strokeStyle for Lua and C#
• Fixed bug where lineCap did not have any affect when using line() drawing function in all environments
• Fix fullscreen bug that caused extra padding when clicking escape
