CMovieBrowser: remove hide() from destructor

hide() in constructor could make problems on created moviebrowser instances
if gui functionality of moviebrowser is not required, eg if only members are used without gui.
Gui parts could be unintended removed from screen.

Note: hide() must be called explicit now. I didn't found any problems at the moment, but
please report if you found problems, so we can fix it.
