Raw output button visibility issues

[nbcl-maronoff]

There's a preference in the main Settings app to enable/disable the bug button. However, the preference only seems to take effect after you move wsabi into the foreground for the SECOND time after changing the preference. That is:

• Open wsabi. Preference read correctly.
• Switch to settings app. Change preference.
• Switch back. Setting is now incorrect.
• Switch away again, not changing anything.
• Switch back again. Now the setting is correct.

This is a low priority bug, to be sure.

This appears to be the case for all preference-related items. Is it possible that we're reading the preference data in the wrong place? (i.e., should it be read in viewDidAppear or something instead?)
