SeekHandle content

I wanted to use the SeekHandle to show the current time but as far as I could tell it only contained static content, I made this change to allow the content to be updated.

Is this its intended purpose or am I playing with something that has another a different job?

Store last seek time in the Flash tech
Instead of caching the last seek time at the player level, cache it in the Flash tech. The only place this value was used was in the progress controls when Flash was loaded, so this simplifies the logic in that component and pushes the hack down into a single location at least.
Fix touch detection test on non-touch devices
TOUCH_ENABLED is false on non-touch devices which causes our minified API test to fail when opened in a browser on a traditional destktop machine. It worked fine through the command line because apparanetly phantomjs supports touch events (ha!). Check to make sure the property is not undefined instead.
