[Cctools-cchost] checkin: 5.1.2 compat and email notifications

[Victor S. <fou...@gm...>]

New feature: users can get email notifications when they have been
reviewed, replied to, rated and remixed. They can also sign up to get
notified when other folks have either uploaded or been remixed.

To turn this feature on:
- browse to http://your.installation/?update=3D1
- Select 'Allow notifications' from 'Manage Site'/'Global Settings'

A new link will show up in everybody's profile including your own.

Also: a few days ago I checked in the PHP 5.1.2 compat code (we were
pretty broken).
