New snipped urls for regression queries

[giovannibajo@libero.it]

Hello,

I have just updated the shortcut mnemonic URLs to query for regressions on mainline and the branches, as follows:

- http://snurl.com/regressions33
- http://snurl.com/regressions34
- http://snurl.com/regressions35

They query for bugs containing "3.[345]" in the summary (to match the regression stomps), and with milestones set to either of the next point releases (3.3.4, 3.4.1 or 3.5.0). I reckon this is currently the best way to check for regressions in Bugzilla, but we are working to make this even easier in the future (the new known-to-work/known-to-fail fields in Bugzilla being the first step in this direction).

Thank you
Giovanni Bajo
