* Issue 4960: Ignoring and blocking of contacts should work again
* Renamed functions
* This function should be renamed as well.
* We now have a frontend to block and ignore public contacts
* Hide some parts for public contacts
* Removed notices, public contact is now accessible from dirfind as well
* We now show contact conversations and contact posts
* We now use a new conversation mode
* The update functionality is disabled until it will work completely
* Fixing tabs chaos
* Update after posts on the contacts page will now work
* Show connect link
- Add CSS changes to support both <a> and <button class="btn btn-link">
- Removed unnecessary "return false" in onclick attributes
- Simplified tabs in profile page to native Bootstrap behavior
