Implement importing profile from a generic URL 

ParseUrl extended to parse generic URLs and parse
the path. DownloadProfile() function re-factored
for reuse with generic URL.

Also:
- INTERNET_FLAG_RELOAD added to the request
  call to force reloading the data from server instead
  of using possibly cached data.
- Input box for URL extended in length to about
   50 characters wide.
