[dev] [spacebed] options: bottom, right

I really like spacebed + surf. Ditched uzbl :)

I am missing two options though:
- display spacebed on the bottom of the screen
- display new spaces on the right instead of left

I think these shouldn't be bloat or hard to implement.

While on this, I noticed dmenu uses the flag "-b" for this. Why was it
decided to not make it an option in config.h?

Anyways, I'd really like this in spacebed, too. Don't really care about
config.h option of flag. config.h seems cleaner, though.
