I fixed problems with the feed when the user uses a full URL as input:

• The regex didn't recognize profile names that include dashes.
• I made the use of www. in the URL optional.
• Some URLs in the generated feed were incorrect which led me to clean up the code some more.

Other fixes and changes

• I fixed a typo in the name of the profile parameter.
• I now better understand the flow of bridge classes and realized that the caching functions I made aren't necessary. So, I removed them and now I instead collect all data in collectData and store them in properties if I need them in one of the getter methods (getName, getUri, etc.). That way the code way more straight forward.
• I also added type declarations.
