Andy McFadden 4f9af30455 Progress toward new assembler configuration 
Rather than have each assembler get its own app config string for
the cross-assembler executable, we now have a collection of per-
assembler config items, of which the executable path name is one
member.  The Asm Config tab has an auto-generated pop-up to select
the assembler.

The per-assembler settings block is serialized with the rather
unpleasant JSON-in-JSON approach, but nobody should have to look
at it.

This also adds assembler-specific column widths to the settings
dialog, though they aren't actually used yet.
