Add cache ruleset and rulesetType to deal with recent-updates view
Refactor recent-updates view to get rid of the timestamp parameter
Rename function for better readability
Remove duplicated micro-updates, if found

Main problem is the view returning HTML instead of JSON or XML; but that would complicate the JS code as each element has a bunch of tags.
Add adapter to list urls to be purged
Update translations
