Loading the last modified binds file should break with Odyssey

[alterNERDtive]

While I can’t test (no Odyssey, duh), simply reading the last modified <preset>(\.(4\.0|3\.[08]))?\.binds file should break; upon writing the 4.0 (Odyssey) file it is copied over to Horizons by default, making the Horizons one the last modified; but loading into Horizons will strip the Odyssey-specific binds.

tl;dr: I’m actually going to have to go by file name. Load 4.0 if it exists, otherwise 3.8 if it exists, otherwise 3.0 if it exists, otherwise plain.

So I’m not sure what the deal with these 3.8 files is or is not (see #16), but Horizons definitely reads them (or other arbitrary 3.x, 4.x files) then writes to 3.0.

So … until further notice I’m going to assume there’s 4.0.binds and 3.0.binds and plain binds.

Fixed for 4.1, forgot to include in commit message.
