- count() returns very different results and never a boolean (not even false on
  error condition).
- therefore you should NOT use it in boolean expressions. This still *can* be
  done in PHP because of its lazyness. But it is discouraged if it comes to
  more clean code.

- use dba::is_result() everywhere (where I found the old, bad way)
- converted some spaces -> tabs for code
- converted some CRLF -> LF as mixures of both is not good

NOTE: I didn't add "AND account_removed = 0" to facebook.php because I don't
have a clone of the addons repository. Please someone do that for me. Thanks.

Please check carefully. I tested locally on my server, but not with other
servers.
