timer.c: skip intermediate timer intervals
"timer_inc()" now checks how many trigger intervals have passed since a given timer has been updated. This might be due to "negative clock skew" (think of summer time) or the fact that some processing took too long (i.e. fetching of a web site). These missed trigger intervals are then skipped and the user is notified so that he may adapt his timer settings. This handling is essential, otherwise unprocessed timers might stack up and would trigger continuously while at the same time becoming notoriously late and unreliable. git-svn-id: https://ssl.bulix.org/svn/lcd4linux/trunk@1141 3ae390bd-cb1e-0410-b409-cd5a39f66f1f
