fix: properly check friend list limits (#1300)

* fix: properly check friend list limits
added a config for friend list limit for the brave that want to mod the client to sanely go over 50
moved the best friend limit config to chatconfig.ini where it should be
cleanup loading these configs options a bit

Tested that the BFF limit works and that the new friend limit works as well

* fix typo

* fix member variable naming
