<h3>Log Message</h3>
<pre>Clarify error message for a user attempting to register with capital
letters on a multisite install.
Because WP multisite does not allow a user to register with capital
letters, we need to do an explicit check for capital letters and throw
up a better error message to avoid confusion.
Fixes <a href="http://buddypress.trac.wordpress.org/ticket/5175">#5175</a>.</pre>
