get_all_theme_objects and directory starts with dot

[Yaju Mahida]

We use subversion and under each sub-directory of Mahara a directory called .svn is created by it.

The logic in the function get_all_theme_objects and $subdir != "." && $subdir != ".." doesn't skip .svn directory which generates [WAR] 09 (lib/mahara.php:639) The name of the theme '.svn' contains invalid characters.

I have modified the logic as if (substr($subdir, 0, 1) != "." && is_dir($themebase . $subdir)) which solves the issue - ignores all directories with dot and double dots.
