Support for webOS phones (tested only on pre3)

Hello, I've modified your great application to work with the smaller screen of the webOS phones.
I own only a pre3 so I'm unable to tell if it works on other resolutions than 480x800.

Also, it seems the search is broken (works with the dummy list in browser, not on the device. I do not own a touchpad so I can't test there).

The controls are using now images instead of text.

Some screenshots:
