Utilize select_related() for user & user profiles. This commit also removes the caching of the avatar URL in the avatar template tag. This is because we are now using select_related, so we already have the profile & avatar when we get to the tag. Thus we don't need to waste time querying the cache. Removed an apparently unused member map template as well.

tinyMCE.addI18n('en.paste_dlg',{
text_title:"Use CTRL+V on your keyboard to paste the text into the window.",
text_linebreaks:"Keep linebreaks",
word_title:"Use CTRL+V on your keyboard to paste the text into the window."
});
