Specifically, this impacts profiles. It appears that relx as a whole requires its configuration to be merged in one tuple order (New takes precedence over Old), whereas the overlays require the opposite (Old takes precedence over New) since the operation order on disk is important to work well. This patch reorders overlay values such that the overlay of a profile takes place *after* the basic overlay, ensuring that the profile actions take place after the basic ones; this allows profiles to properly overwrite files as expected (see erlang#1609) This is done while adequately maintaining the order of operations that were required as part of erlang#1563 Overlay vars of profiles are also checked to be working fine, along with a test. This fixes erlang#1247 and erlang#1609
