Use the Left and Right keys to switch between divecomputers

Browse source 
The existing code had the somewhat retarded Ctrl-C binding for displaying
the next divecomputer and no way to go back to the previous one. With this
commit we use our keyboard grab to map Left and Right to previous and next
divecomputer. Much nicer.
