Simple plugin that replaces the "request new password by username" functionality with one that uses the user's email address and offers both password reset and username request. If more than one user has the same email address, it returns the user with the lower guid (shouldn't be an issue with newer installs).

This can serve as an example of how to override functionality in Elgg (overriding registration would be similar).

This has been tested with 1.5, 1.6 and 1.7.  It will work with the default theme for 1.5-1.7 out of the box as long as the groups plugin is enabled.

To upgrade from the previous version, just copy the files over the old ones.

Changes from version 1.5: work around for Elgg 1.5 core bug and unvalidated users receive another validation email if they request their password (just like the default Elgg 1.5)
