Atom package: Black lines in minimap

[jmanuel1]

I think the minimap package does not understand that we're doing syntax highlighting. In fact, the Grammar subclass doesn't return any tokens in tokenizeLine which I think explains why the lines in the minimap are black. Atom's grammar tokens are supposed to collectively cover the whole text, but our grammar tokens cover none of the text because there are no tokens.

Possible solutions:

• Have a textmate grammar. Use the Concat lexer to overlay extra information on top of it.
• Give Atom the currently known tokens when it asks for them from the grammar. We get the tokens asynchronously, so maybe what we display will be out of date.
• Plug into the minimap package.

I'm not of fan of the second option.
