Ensure window manager gets a refresh when the Schema debug console is hidden.
Style tweaks.
Fix issue with debug console reset. Throw some more telemetry and exceptions into the app cache monitor routine to tighten the noose on Firefox's badly behaved callbacks.
Console.log now also writes to Schema debug console. More special case handling inside the appcache monitor for Firefox.
More appcache monitor fixes. Schema 0.847 "seems okay" in Firefox, IE 10, Chrome, and Webkit. Chrome and Safari seem like the only two browsers that do a half decent job with application cache events currently. IE10 is a bit quirky in that it seems to want to download the app cache twice when an update occurs. Firefox is just psychotic: app cache events seem optional forcing you to evaluate a state machine on a delayed timer to assess actual app cache state vs. where you think you are based on the callbacks that you've received.
