Refinements to GoSublime-Go syntax

[brynbellomy]

Extracted a lot of the existing regexes into the repository section of the syntax, so that they'd be reusable. Also added some new stuff.

Happy to refine this further if you have ideas/thoughts.

Screenshots

• Struct field tags are highlightable

• In-function var and const blocks
• Struct and slice literals

• Method receivers and their local instances are scoped separately

... etc.

Perhaps these improvements can be submitted to the https://github.com/ironcladlou/GoTools project as well? It is actively maintained. I've switched to it from GoSublime.
