In the original lualoader project, 'escapef' and 'escapeb' were chosen for
'escape fg' and 'escape bg'. We've carried on this naming convention, and as
our use of attributes grow the likeliness of 'escapeb'/'resetb' being
confused upon glance for 'escape bold'/'reset bold' increases.
Fix this by renaming these four functions to {escape,reset}{fg,bg} rather
than {escape,reset}{f,b} for clarity.
