Prep work for multi-encoding support Wrote down research into C64 encodings. Added source for a first cut at 2016-char-encoding test.

Rework 201XX-char-encoding-X tests We have a single character-encoding test that is cloned 3x so we can exercise the different values for the project's default character set. It was a 65816 test because it tested 16-bit immediate char operands, but that's a very small part of it. The 65816-specific portion is now 20122-char-encoding. The rest is now 201{2,3,4}0-char-encoding-X.

Add C64 encodings to instruction and data operand editors Both dialogs got a couple extra radio buttons for selection of single character operands. The data operand editor got a combo box that lets you specify how it scans for viable strings. Various string scanning methods were made more generic. This got a little strange with auto-detection of low/high ASCII, but that was mostly a matter of keeping the previous code around as a special case. Made C64 Screen Code DCI strings a thing that works.
