Fix missing sound on Decolored Squares

__**Decolored Squares:**__ Always move on to the next square. Manual reprint required if you’re a stickler, but it should be fairly clear that the tapped square now turns white.
__**Discolored Squares:**__ Fewer active colors to make the module less laborious.
Also changes to flavour texts, plus minor wording fix in Varicolored (unique → distinct).

Fix TP handler exception.

Regularize the logging tags so Logfile Analyzer doesn’t need special-casing.

Varicolored Squares minor wording fix in manual.

Major change: NEW MODULE: __**Decolored Squares**__
