Optifine Check

⚠ Warning! This release is incompatible with existing setupts as the config system changed!

• Added new config system
• Added option for only displaying the GUI once (saved in a config file)
• Download mode can now be toggled between 'FORCE' and 'REMIND' instead of using numbers
• Detection mode can now be toggled between 'MISSING' and 'AVAILABLE' (see below)
• You can now specify multiple classes instead of only one (in case of version changes)
• The code has been cleaned up.

You can now use this mod for much more than just detecting Optifine. In theory, you can use it to force/prevent the usage of any mod.
If you change the mode to 'AVAILABLE', the game will not load if any of the listed classes could be detected (can be used to prevent simple hacks).
