Jira cleanup

FYI: I spent some time cleaning up Roller's Jira. I closed all tickets 10
years old or older and I closed a bunch of old feature requests that we are
not likely to implement. I also attempted to set priority on the 34
remaining tickets based on what I thought was most important. You can find
the resulting list of issues in priority order here:

https://issues.apache.org/jira/issues/?jql=project%20%3D%20ROL%20AND%20resolution%20%3D%20Unresolved%20ORDER%20BY%20priority%20DESC%2C%20updated%20DESC

I plan on reviewing and culling down the remaining issues at a later time.

Please feel free to re-open any tickets you might want to work on.

Cheers!
Dave
