Add 'overrides' support

[bisubus]

Can we consider adding overrides support in project's bower.json or as an option object? The same way as wiredep and main-bower-files do. Fortunately, it should be limited to main keys.

Passing overrides as an option would be also great because it provides some opportunities of the decisions during build process.

This would also solve #19.

+1 Honestly, I have a second request to this, which is to generate a vendor.js file that requires every bower main file (using overrides as necessary).

This would definitely be valuable. right now trying to figure out how not to include the scss from bootstrap that's in there by default...

[bisubus]

@thedamon Invaluable, I would say. Right now I'm parsing package bower.jsons on postinstall and injecting main from project bower.json overrides there. It does the trick but feels wrong.

Looks like I should be able to use the 'excludes' option to cover me here at least..
