user_stats 6.x-1.0-beta1

Practically an entire rewrite of the module, please test this works for you before upgrading!. Here are the highlights:

• no more dependency on profile.module! User Stats now has its own tables;
• Views 2 integration -- including some default views for Top posters, Online users, and and advanced IP address tracker (for easily finding spammers) in the Administer -> Reports section;
• Actions/Rules integration -- react to users being signed up for a number of days, or post count increasing/decreasing. For example, a role could be added to a user account when they have over 10 posts and have been a member for 30 days;
• efficiency improvements;
• added README;
