Swiftlint: Disable multiple rules with one comment

[AndrewSB]

I think it would be cool to be able to put

//swiftlint:disable:next variable_name trailing_whitespace

and have it disable both of those rules for the next line. Currently, to achieve something similar Im doing:

//swiftlint:disable variable_name
<offending line of swift code> //swiftlint:disable:this trailing_whitespace

+1 agree with that
