JSHint code correction needed for build: Confusing use of '!'

[simonarbuckle]

The following warning is breaking the build and needs to be resolved by code correction:

aria/templates/NavigationManager.js jshint results

line 93, col 60, Confusing use of '!'.
line 93, col 83, Confusing use of '!'.
line 94, col 29, Confusing use of '!'.

I would prefer to suppress this warning but it seems it is not configurable at the moment, therefore the only other option is to correct the code.

This is related to issue 578 on jshint which is not going to be fixed anytime soon

This has been fixed by commit d882661. Now in build/visitors/lint.js we can define additional JSHint errors to be ignored, if they're not configurable in JSHint itself.
