Change "last started" status output for check program to be last start time of start program

[jeremy mayes]

The current output is a bit confusing for people. Everyone using monit on my team interprets that time stamp to be the last time the start program was executed, but, it's the last time the check program was executed. There's already a "data collected" time stamp which make sense that it's the last time the check program was executed. Can the start time be changed?

Fix Issue #358 : Drop the "last started" report for a "check program" ... confusing as users interpret it as the timestamp of services' start program, not timestamp of check program execution. The information about last program start time is not very important as it is driven by the schedule + there is a "data collected" timestamp too.
