Quarantine event

Initial implementation for #27 

I am not able to figure out why it's not able to read a database from the disk when command line utility works.

sqlite3 /Users/$USER/Library/Preferences/com.apple.LaunchServices.QuarantineEventsV2 'SELECT * FROM sqlite_master WHERE type="table";'

sqlite3 /Users/$USER/Library/Preferences/com.apple.LaunchServices.QuarantineEventsV2 'SELECT * FROM LSQuarantineEvent'

Are working fine - but reading from code again crashes.

P.S.: I am sorry - I have to figure out how can I get rid off  that crontab.
It looked to me that create is in fact open where instead of path to file is ":memory:".
