Devotion statuses fixed. Cleaned some warnings. Unit range shortened!

- Now SC_AUTOGUARD and SC_REFLECTSHIELD won't have effect if the devotion range is too big. Bug report http://hercules.ws/board/tracker/issue-8345-about-devotion-status-tra/
- Cleaned some warnings
- Due to the exploit of some client edits and with the feedback of some users, I can say it's safe to change back the range extra cell to 1. Thanks Juvia, KeyWorld.
