Make it possible to subscribe a linter to files of any type.

Currently, LinterView::initLinters() checks to see whether the grammar of the current file is in the linter.syntax array when deciding whether to register a linter. For performance reasons, this makes a lot of sense, but it would be nice to be able to specify a wildcard to say "always associate my linter."

I am trying to add a linter for Arcanist, which has an arc lint subcommand. Basically, you can have a large project of all sorts of source files and register linters for them and arc lint <filename> will run the appropriate linter(s) and print the results. Therefore, I want to run arc lint whenever any file is changed in Atom. In this scenario, Arcanist is responsible for mapping file extensions to linters. Since I am already using Arcanist, I don't want to duplicate this information in Atom.

My current thought for a workaround is to do:

    syntax = atom.syntax.grammars.map(function(grammar) { return grammar.scopeName; });

This exists. Just use a wildcard (*) in your grammar scopes.
