(Array) pop_front, pop_back return values

pop_front, pop_back now return values instead of `void`. Things
I didn't know how to properly implement:

1. pop_front & pop_back shows in the help menu Object as return value.
   I know this is incorrect but if not Object than what? Cause it
   can't be void. It needs to be a generic type that includes all the
   Array types
