Add a PAGEKEYS option to POPUP to make navigation easier
Brought to you by:

If POPUP would recognize the PageUp/PageDown keys, navigation of large selection lists would be easier for the user, requiring fewer keystrokes to get to the next page.
This would also make POPUP more useful for displaying text, without having to create a file to do it.
Scrolling behavior should be the same as the filearea, i.e. fullscreen-1
Added PgUp/PgDn support.
RC4: Working as requested.
