Experimenting with speeding up the installer.

Added support for foreign keys to the MySQL adapter.
activity_stream_matches now has a foreign key to help enforce referential integrity.
Added the AddForeignKey method to the database adapters.
Shortened a couple of API bits to ever slow slightly reduce the lengths of the strings.

Fixed a phrase group I missed for logged out users in init.js
Fixed a bug where deleting a topic would break the alert list when there is an alert event relating to it.

You will need to run the updater / patcher for this commit.
