Use scriptrunner issueFunction to speed up things

Original code needed per-project JIRA definition because JiraUpdated was
querying all JIRA issues in a project that changed over defined period
of time. This was wasteful and for JIRA instances with scriptrunner
installed we can do things faster and with a single configuration

With this change:
 * project configuration is optional - if omitted all projects are
   reported
 * added new "login" config item needed because when lastUpdated('by
   <login>') is triggered with non-existing login name it causes failure
   of the JIRA plugin.
 * JiraUpdated really only reports comments and does not report other
   changes such as state change (this removes duplicate when closing issues
   as a side-effect)

This will need further rework so that use of scriptrunner is
optional/configured properly (since it's not part of JIRA itself).
