Add delay between updates of tracking file

[IvanBond]

Currently RC updates tracking file at each cycle - each minute. OneDrive sometimes can't handle such frequency, so need a configurable delay-parameter.

smth like ' update activity file each 10 min If ActivityTrackingFileUpdateTime <= Now - TimeSerial(0, 10, 0) Then Call UpdateActivityTrackingFile ' update file which can be used to check that Report Controller is online from external app ActivityTrackingFileUpdateTime = Now End If
