[arm/release] fix: Removing case sensetivity from stat names

commit 624f13d79870fbbc1e47f17d97d105a24d12d54e Author: Damian Johnson <atagar(a)torproject.org> Date: Thu May 19 09:57:18 2011 -0700 fix: Removing case sensetivity from stat names When making a graphed stat selection arm would crash if the string used for the stat key contained capital letters.

[arm/release] Dropping the last raw TorCtl usage

commit c21dbc32601b467968c0a900f0b79c2738b7d1e3 Author: Damian Johnson <atagar(a)torproject.org> Date: Sat May 14 14:11:56 2011 -0700 Dropping the last raw TorCtl usage This removes the last direct usage of TorCtl by arm. Instead, all access is done via the torTools Connection wrapper class.
