3 new classes

Today I have released three new classes.
Catcher, PayPalButton and SiteMap.

Catcher extends PHP's error- and exception-handling by the possibility to decide if the error-messages should be printed to the screen, logged into a file or mailed to the admin.
It also can include a backtrace to the real source of the problem, as this might sometimes not be obvious from the error-message.

PayPalButton creates buttons that can be used for payments using PayPal's Website Payments Standard.

SiteMap easily creates XML-sitemaps that can be used for to pass to Google for indexing.
