Add ability to target keywords that take you out of the normal flow of execution

TS and JS Grammar Extension version: 0.0.41 / latest

I'd like to be able to highlight keywords that take you out of the normal flow of execution. By this I mean keywords that cause code to jump somewhere else when running. For example return, throw, break, continue.

Because these keywords take you out of the normal flow of execution they are very important, and not something you'd want to miss when scanning code, so I think it would be great if we could target them separately to ensure they aren't missed.

I'd like the ability to highlight them as more important when compared to other keywords such as if, for, while, try, catch, etc.

Currently break and continue are in the same scope as for, while, do, etc (keyword.control.loop). And throw is in the same scope as try and catch (keyword.control.trycatch). Because of this it isn't possible to highlight them separately.

Example:

In the screenshot above I want to highlight continue and throw, but doing so also highlights for, try and catch whereas I'd like those to remain grey.

VS Code、Sublime Text、Atom の各 grammar で使用されている TypeScript TextMate grammar ファイルから始め、return、throw、break、continue に割り当てられている scope を、既存のループおよび try/catch キーワードと比較して確認します。これらの終了フローキーワードに独立してハイライトできる個別の scope が割り当てられ、for、try、catch の scope を変更しないことをもって完了とします。
