Make it easy to just get the avatar URL

[hempsworth]

There is no easy way to just get the avatar URL, all of the available methods:

bp_displayed_user_avatar()
bp_loggedin_user_avatar()
bp_core_fetch_avatar()

all return the entire <img>. I've slightly modified these functions to allow just the URL to be outputted. Completely backwards compatible, and negates the need for hacks like this.

Now, to get the URL all you need to do is:

bp_displayed_user_avatar( 'url=true' );
bp_loggedin_user_avatar( 'url=true' );

(In [3086]) Fixes #2436 and adds some documentation to bp_core_fetch_avatar

hempsworth: The $html argument was added, and set to true by default.

If you use...

bp_core_fetch_avatar( array( 'html' => false ) );

...you will simply return the URL of the avatar with no <img>
