Chat Calc

Fixed custom functions parsing allowing malformed functions that broke the config.

I apologize if this spammed anyone's notifications, I was testing out another way of publishing the mod updates.

Updated to work with 1.21.

Nothing seems to be broken, so all I did was change the mod's metadata to allow 1.21. This should make things easier for those who don't know how to override mod dependencies.

New Features

• Added support for binary, octal and hexadecimal numbers (Closes Issue #1)
• Added calculations on signs. Might as well take the chat out of chatcalc.

Fixes

• Trying to fill in the result of an equation will no longer delete the = character.
• Moving the cursor between the last and second last character of a calculation will no longer ignore the last character. (For example, when the cursor was between 3 and 0 in 5*30, the calculation would result 5*3=15 rather than 5*30=150.)
• The links this mod provides to other things should now point to the correct pages. Also added the missing few links such as issues and mod homepage. (Example: the Source link in ModMenu was pointing to the upstream repository rather than this fork's.)

Updated for 1.20.5 & 1.20.6
