Title: New Options, delay and sequence logging options

I use this modified generator plugin to trigger some custom filters every second as a heartbeat/pulse.

Added two options:
delay => #in seconds, delay between each event generated. Default => 0
log_sequence => Wether to add sequence number to the event. Default => true
