Added functionality to select swipeable directions

[kh0r]

I needed up/down functionality and made your library configurable - See #30. The default behaviour is still horizontal. But now you can change swipeable directions with the new direction attribute.

+1 Would love to have the 4 main directions swiping (up, down, left, right)

Why isn't the commit conflicts have not been resolved. according to my understanding kh0r's solution has not been committed due to conflicts. So does that mean I can't use this library for swiping up and down. :(
