Menu entries: own programs for Reset Screen Layout and Hide/Show Screens

Reset Screen Layout and Hide/Show Screens both ran ft-layout. Steam lists
entries by program, so Hide/Show launched Reset. Each gets a wrapper.

From PR #17 (only this part of 9618be8; its host_command change is for the
Nix packages).
