hitaar: new theme

Hello @thomaspark,

I am totally heartfelt and joyous with the success of Flatly and also see that people are requesting for a version of Flatly; so here I am with a quick, to-start-with and a decent version of Hitaar: A night-mode view of Flatly. This is totally keeping in mind https://github.com/thomaspark/bootswatch/issues/191 and https://github.com/thomaspark/bootswatch/pull/224.

Feedback from you is most welcome. I insist on the name 'Hitaar' although I think we can work something out for a sub line.
