Allow using greater-than and less-than mathematical expressions in version list

[RealTriassic]

Currently, you have to add in each protocol version for each version you want to support one by one, it would be a lot nicer if you could do >755 as an example to allow everything after protocol version 755 (1.17).

I have plans of recoding the plugin, including the usage of my ExpressionParser, which would allow stuff like {userVersion} < 766 && {userVersion} > 762
