Allow overriding keystrokes

Context: I'm a longtime Mac user, and among other things this means I have deeply ingrained key-stroke habits from the things supported by CoreText. This includes being able to transpose characters with Ctrlt.

For obvious reasons, this plugin doesn't play particularly well with that. I'd be perfectly content with just being able to manually remap all the keybindings to handle it.

Aside: I actually used the transpose action in this very writeup, so I duplicated it as a GIF.

まず、TypeScript Sublime plugin が keybindings を定義またはインターセプトしている場所を特定し、次に Ctrl-T が要求された transpose アクションとどのように競合するかを調べます。ユーザーが plugin の keybindings を手動で再マッピングでき、transpose のキーストロークを引き続き使用できるようになれば完了です。
