* Checks for Textpattern updates.

* This function uses XML-RPC to do an active remote connection to

* rpc.textpattern.com. Created connections are not cached, scheduled or

* delayed, and each subsequent call to the function creates a new connection.

* These connections do not transmit any identifiable information. Just an

* anonymous UID assigned for the installation on the first run.

* @return array|null When updates are found returns an array consisting keys 'version', 'msg'

* @example

* if ($updates = checkUpdates())

* {

* echo "New version: {$updates['version']}";
