[FEATURE] Alternative Pagination traits

[guiwoda]

Alternative Pagination traits to (sort of) decouple from Laravel's Request.
Two Traits were introduced: PaginatesFromRequest and PaginatesFromParams. The previous Paginatable trait was kept for backwards compatilibility, but PaginatesFromRequest should be favored.

TO DO:
See if doctrine/orm#6180 passes so we can actually unit test this.

@patrickbrouwers Do you think we could integrate this as is, then somewhere along the road add database integration tests for it?

will you update the documentation?
