Fix various nagging package issues.

Misssed typo

Check with get_pkg_id() if the package is installed. If it is not, continue on to next element

Version bump

rmdir_recursive: Handle single files and remove an extra foreach.

Make sure we remove the package's XML file.

Fix a typo. This broke package deinstallation.

Brute force delete a package if it still exists after unlink_ifexists()... the item in question is most likely a directory.

Don't attempt to run package deinstall commands if the package XML hasn't been parsed (or it doesn't exist).

Honour the custom_php_deinstall_command which is in about 90% of our packages!
