Title: Main Window UI Improvements

This pull requests address issue #6.

I replaced the ```NSSlider``` with two ```NSPopUpButtons```, (one for hours and one for minutes). This will update both increases usability and introduces fine grain controls over the block interval.

The updated code continues to honor the ```MaxBlockLength``` preference (rounded down to the nearest hour).

Lastly I added the SelfControl icon to the main window for a little bit of flair.
