button in user's setting to resend relocate message to contacts
option in admin's site setting to relocate a server

Added a switch to suppress displaying of the tags.

1. Add template category 'end' that places content right before final </body> tag
	2. Move most Javascript from tpl files into one cacheable file, theme.js
	3. Load scripts at end of the HTML document instead of in the header
	4. Minify several Javascript files

Note that the second and third things were only done for Frost and Frost Mobile. Doing it for every theme means going through every .tpl for every theme and rearranging the Javascript, which is tedious.

also hidewall wasn't properly checked before sending 'xxx is friends with yyy' messages

Load optional "config.php" from theme folder and show in page.
Loading of "config.php" follow theme_info['extends'] property.
