Correct scope for var keyword

[pchaigno]

As reported in #33, the current scope for var is incorrect. This PR changes it to storage.type.source.cs.

It's weird. I didn't see source scope for symbols in other languages. source scope is usually "root scope" like on the screenshot.

I created an issue #35

Also add var please
I think it should be storage.type.source.cs -> storage.type.var.cs.

I agree. Those source scopes seem weird.

I didn't see source scope for language symbols in other languages.

I only added it to stay coherent with the other scopes. I find it weird too.

I think it should be storage.type.source.cs -> storage.type.var.cs.

Why var? The examples in the TextMate naming conventions are always storage.type.language-name.

I see

More subscopes let us more possibility of customization. Yes, there is no storage.type.var in the TextMate but also there is:

...You should however append as much information to the sub-type you choose...

TextMate docs are very unclear. I created an issue before writing clear docs for Atom. My bad.

Okay, makes sense.

@50Wliu I think this is ready :)

Var needs to be removed in the match above this line

[pchaigno]

Done. Thanks!
