Add isize and usize types

The decision.

Thanks! The .tmLanguage is generated using AAAPackageDev though. I've added your changes in the JSON file, too.

When is it planned to remove the int/uint and i/u terms from this highlighter?

It was suggested to remove them immediately from the vim syntax highlighter (rust-lang/rust#20881), as this shows their deprecation.

Also, when does this get pushed up to github/linguist?

Thanks.

[jhasse]

Good idea. If someone opens a PR I will merge it right away, otherwise I
will do it in the following weeks ;)

Don't know about linguist. Are they using this plugin?

[brookst]

Yeah, I got here from linguist. This plugin is linked as a submodule in https://github.com/github/linguist/tree/master/vendor/grammars. I assume that means githubs syntax highlighting is using this plugin.

I'm not a Sublime Text user, so I don't really want to start hacking at it without a way to test.

@jhasse I think we should wait a little bit, at least until the beta version of Rust.
