Major changes to design, layout and functionality

Added menu-bar
Added search/filter (search is only for numbers, mostly usefull for mobile input)
Added info
Added randomizer
Added seeking to playback
Added toggling of whole title, just click header

Improved styling on whole app
Improved flex on whole app (header should not shrink/grow anymore)
Improved mobile display (should be more compact)

Changed button actions to use controller functions (apparently it should work fine from homecontroller, not from maincontroller)
