Remove the cap on ability and attack bonus

[Anonymous Lemur]

NWN EE has enabled the ability to easily allow abilities to go above +12 and attack bonus to go above +20. It's rare that anyone manages to even come close to these boundaries, but it does happen and I'd like to see the caps on them removed.

It seems like a very easy thing to set too and would make things like true strike function as intended as well as reward barbarians who focus less in strength and more in charisma a lot more than the current system.

Here is the thread that details how it can be done: http://blog.beamdog.com/2018/02/nwnee-8157-8158-patch-notes.html
