* Added LinkReceiver methods that return the length of the string.

Browse Source 
* AS_GET_STRING_WIDTHS now uses this method to send the strings to the app_server;
  ie. it no longer sends the whole strings, and it saves sending the string length
  separately.
* BFont::StringWidth() will now always return 0.0f in case of an error (instead of
  some random value)
* Minor cleanup.
