Possibility of allowing users to create custom syntax highlighting

[DatCheese]

Hello,
In threads I frequent and a lot of others frequent we use Wiremod's Expression2 entity which allows you to program in a language similar to lua yet different.
It would be nice to be able to create custom highlighting for this language in the forums. Highlighting for this language has already been created in Sublime for reference.
