All Nixtape views now catch Exceptions thrown by the User class's
constructor.

In most Nixtape views, code that instantiates User objects is now
encapsulated in try...catch blocks.

All code instantiating Artist objects has been encapsulated in
try...catch blocks. This should help solve some potential problems with
invalid artist names.

This should resolve issue #246, though a more thorough analysis of why
the artist isn't found in that case would be nice.

phpDocumentor's @return tag syntax is:
@return datatype description
@return datatype1|datatype2 description

Make popular artists cloud based on loved tracks (removes the need for a cronjob to create it from scrobbles)

Removed last character from default base_url in nixtape install because default with slash gives urls like nixtape//url.php

Added clarification about nixtape database being the same as the gnukebox one. Added *help* link to install guide to the bottom of the install pages

Added full <?php tags to the top of all PHP scripts. Removed ?> tags from the end of all PHP scripts.
