regressive delete problem with roku UP after delete

[rshendershot]

this may have been fixed but due to Issue #16 I can't try it. It would be a big problem in a channel release.

When I delete I'm returned to categories[0] in the main screen. I wish this was the top level menu instead, but... I press the Roku UP key and am presented with the detail screen of the show I just deleted. If I chose delete then some other show will unexpectedly be deleted.

after Delete we need to more carefully re-initialize internal data

after deleting, clicking the UP brings up the deleted detail. choosing delete again causes an illegal reference and my Roku drops into debug. (zane-master 20130605)

I implemented a fix for this issue. I should note that users may experience some quirkiness with the pagination. Nothing serious. Just that a video may be repeated from one page of the list to the next. Simply hitting back/up and reselecting the directory will refresh the list and the pages. I thought about fixing the issue but it appears to be a fairly pervasive fix and I would rather spend my time refactoring the UI. So I think I will mark that issue as an acceptable risk for now.

The problem is that when traversing backwards though the screens the UI needs to refresh every screen in the stack. This is not an easy fix because of the way the UI is designed (mostly because it is based on the SDK videoplayer example. I need to think about this some more.
