Work in progress.
Updated code fomat in test Jasmine.
Added hard-coded flag to video.html that turns on/off autohiding of captions.

Front-end functionality was not removed. When flag is set to "True", old
behaviour of autohiding of controls and captions will be enabled.
Added functionality to show captions on "CC" button mousemove.

When auto-show/auto-hide is disabled, the captions will be shown when
the user will move the mouse over the "CC" button. They will then
auto-hide after a while if the user doesn't continue to move the
mouse over the "CC" button, or over the captions themselves, or use
the keyboard to select a specific caption. If the mouse pointer is not
over the captions or the "CC" button, they will hide after a while.

over videoplayer itself for PKU videos.
