Shared User Table Roles

When sharing the user and usermeta table between multiple wordpress
installations using the same database, any role given to the user is only valid
for a single wordpress installation.

This plugin ensures user roles, user capabilities and user settings are
shared between the multiple installations. This is configured using a wp-config
constant.

Any role set in any of the installations will be reflected in all other
installations.

Caveats:

• Compatability with wordpress multisite is unknown
