New issue 625 by janne.t.harkonen: Rename function `rebot` to `run_rebot`  
in `robot/__init__.py`
http://code.google.com/p/robotframework/issues/detail?id=625

Function rebot() clashes with submodule rebot, making it impossible to  
import the latter.

We decided to fix this by renaming the function to `run_rebot`
