Add status bar showing result of last command.
Fix issue with pushToPage where characters like spaces where not encoded.

This caused some commands, like changing mode to XBox 360, to fail.
Only set volume when user finishes slider interaction.

Originally sent a command for every movement of the slider. That worked
OK when sending a value to the server, but it is not working well with
the IR controls, which are slower and more finicky.
Add better descriptions for devices that have no specific controls.
Add system menu.

Provides meta controls for application such as reloading the page and
restarting the server.
Fix sizing of system menu button.

Was referencing by class instead of id.
Load supervisor links in different tabs

Still does not go to Safari on iOS.
Get status in correct place.
Remove reload option and rename server restart.

The reload option was not working right in an iOS home screen app, and
it was unnecessary in any browser (which has its own reload).

Also renamed the server restart option. You're not restarting the manager.
