uc_affiliate2 6.x-2.0

Changes since rc5:

-- the commission was added twice when changing between "award" statuses.
-- don't remove the original admin comment when taking away commissions. Add another one instead.
-- don't try to link to an anonymous user's profile page in the "All orders" tab
-- added an update entry to .install, to remove some (harmless) junk from uc_affiliate2_orders next time update.php is run.
-- to prevent upgrade issues, made a change to the "award" statuses on the settings page. You'll have to select them again.
-- fixed a warning on new installs.
-- affiliate redirects now issue 301 headers on redirect. More SEO friendly.
-- don't remove a click from the count when removing comissions
-- added a more detailed unique clicks view, displaying user ip, if the cookie was set, etc.
-- getting the affiliate id from the cookie doesn't require a trip to the DB anymore.
-- you can now use the product title ([TITLE]) in link templates. [Thanks omerida]
-- fixed a bug in the role handling
