Add W65C02S support, part 1 We were claiming W65C02S, but it turns out that CPU has the Rockwell extensions and the STP/WAI instructions. We need to change existing references to be "WDC 65C02", and add a new CPU definition for the actual W65C02S chip. This adds the new CPU definition, the instruction definitions for the Rockwell extensions, and updates the selectors in project properties and the instruction chart tool. This change shouldn't affect any existing projects. Still more to do before W65C02 works though, mostly because the Rockwell instructions introduced a new two-argument address mode that has to be handled in various places.

// NOTE: these are generally three characters, but the pattern breaks with the Rockwell

// assemblers do). On the 65816 some mnemonics are extended (e.g. LDAL for LDA with

Rename undocumented 6502 opcodes to match Unintended Opcodes doc These *almost* match what cc65 has, and are accepted as primary or aliases by 64tass. This combines the LAX and LXA operations. LXA is the immediate form of LAX, and behaves somewhat differently (and is unstable). I was treating them as two separate operations with independent mnemonics, but that doesn't seem to be the preferred way to handle it. The cc65 generator wasn't generating LAX before; now it does. This required nudging the width disambiguator, as LAX is a second example of an instruction with both DP,Y and ABS,Y operands. (issue #20)
