Disable spellcheck/autocomplete on input

[remulasce]

On GS4/5, TouchWiz tri.es to autocorrect station names upon input.

This is especially bad because the app supports multiple partial names, which get corrected to junk and then become useless.

It's simple, so it's done.

But on second thought, I wonder if anyone is using SwiftKey or something that solves input better than my partial-name autocomplete.

Well it looks like keyboard-level swipe input still works. So, pending confirmation that autocomplete turns off, I will close this.

This is already mostly done, so let's throw it in cycle 4.
