top: map additional navigation keys

Browse Source 
There were some gaps in the alternate navigation keys
top provided.  Additionally, some inconsistencies
existed in the supporting key table.

This commit adds the following new key equivalents,
mirroring the standard vim navigation keys:
. ctrl+alt+ k = pgup, ctrl+alt+ j = pgdown
. ctrl+alt+ h = home, ctrl+alt+ l = end

Also, the supporting table entries now consistently
follow these "directions":
. up/pgup, down/pgdown, left/home, right/end
