MultiEPG: Change OK button to select single channel EPG

The Info/EPG button is still selected event info. Previously the OK and
the Info/EPG button had the same functionality. This also allows when
playing a recording to get single channel EPG via the MultiEPG.
Add option for going to MultiEPG when viewing EPG from recording
Remove InfoBarSimpleEventView from InfoBar as it is not required anymore
Remove obsoleted InfoBarSimpleEventView from InfoBarGenerics
