Merge branch 'hotfix/0.9.0.1'
Bugfix for the case where a suspended user sends a contact message. Their name (with the '(account suspended)' suffix) is marked by the translation call as HTML safe, so escapes the angled brackets when they are appended to it in the contact mailer code. Use string interpolation instead.
Merge branch 'hotfix/0.9.0.2'
Add option to limit memory available to external commands
Limit memory available to wvText, which calls elinks
Use ruby 1.8.7 bindings for backward compatibility
Re-add commonlib rake files
Merge branch 'external-command-memory-limit' of ssh://git.mysociety.org/data/git/public/alaveteli into external-command-memory-limit
Update commonlib to get memory allocation flag for ExternalCommand
Merge branch 'external-command-memory-limit' into hotfix/0.9.0.3
Latest version of commonlib - I don't think the require of 'spec/rake/spectask' is needed, and causes problems in production.
Merge remote-tracking branch 'origin/hotfix/0.9.0.3' into rails-3-develop
