Fix bug where window arrangements were incompatible with custom prefs dir. Improve wording of initial alert w/ custom prefs. Add alert when quitting when there are custom prefs and you've changed something

found a resource leak in PTYTextArea trackingRects.

With long periods of usage, iTerm2 windows slow down while switching tabs.
All of this time, apparently, was being spent in _CGSRemoveTrackingArea().

Instrumenting calls to {add,remove}TrackingRect showed unbalanced allocation caused by -[PTYTextView refresh] being called on tabs after they were removed from view.
This "phantom refresh tracking rect" was then dropped/forgotten when the tab came back into view during viewDidMoveToWindow, which did not verify there was not already a tracking rect.
While there may actually be a more underlying bug with "phantom refresh", this patch should solve the resource/speed leak by guaranteeing we never allocate an extra tracking rect.

When you create a new window while already in lion fullscreen mode, ignore the zoom-vertically-only setting. Fixes bug 1312.
