It's not always the case that $SESSION will exist. Make sure when it doesn't the current_language() function doesn't blow up.

bringin in line with changes to get_users_data

changing search so it excludes the logged in user and bringing in line with changes to function get_users_data()

so user/find.php doesn't include the searcher in the results

changed get_users_data so it preserves the order of users given

added methods common to myfriends.php and find.php for friends control and getting the data for the pages

Don't link to small profile field artefacts from my views; when they are linkable, use the artefact type as the display title rather than the artefact title

I cleaned up the code style and internationalised the language strings.

Conflicts:

	htdocs/admin/site/options.php

Moved the networking template into the correct location also.

Javascript for the site pages admin page. Simplified somewhat from the javascript that was originally inline in the page.

Added javascript file to handle JS for site options page. Enforces reload of the page if certain settings are changed. Fixes #718.

Added a 'reply' method and made it call a PHP callback when a form needs replying to. I'm sure this is badly designed but will clean it up later.

A whole bunch of minor cleanups, adding some short statements to the admin pages so people know what they are fore.

Added callback for the 'replycallback' feature of pieforms, which helps handle forms that can be submitted by both js and non js better.

Named the site pages page more consistently - it's now 'edit site pages'. Deleted the inline javascript, it's now in a separate file.
