Add INFO logging on add\delete\edit actions

[Audrey Gehring]

Adding INFO logging for add/delete/edit actions would be helpful for troubleshooting purposes/tracking.

Hi Audrey,

I've fixed the issue: https://bitbucket.org/dmitry_apanasevich/jira-jigit-plugin/commits/87648b14ab40b8ffcdd9c660c292fab6d7e22505. Now every action will be logged.

I'll publish a new version soon. But, note that the default logging levelis WARN. So, you'll have to switch logging level for package jigit into INFO after update of the add-on.
