Allow choice of foreground and background colors for Medley X11/SDL display (#511)

Browse Source 
* Allow choice of foreground and background colors for Medley X11 display

lde/ldex Accepts -fg/-foreground <color> and -bg/-background <color>,
or the corresponding X resources ldex*foreground and ldex*background
to specify the colors that will represent the monochrome Medley display
pixels.

* Extend screen foreground/background color selection to SDL display subsystem (ldesdl)
