MAJOR: Full rewrite of slash cmd loading system

The system of detecting, comparing & registering slash cmds has been rewritten and updated for future compatibility. This will break all current plugins (so please wait until they are updated)

=> Increased speed
=> All cmd params are now used when comparing
=> Future compability & removed deprecated functions
=> New universal utility interfaces for slash commands
=> And more!
