The theme manager backend for installation is the plugin manager backend, because they are very close. thanks to feature:1502, installing a theme and installing a plugin are very similare operations. The only differences are the installation directory and the main file to find in the archive. This is only the very first step, the "add new theme" screen needs many improvements, to begin with display style. git-svn-id: http://piwigo.org/svn/trunk@5143 68402e56-0260-453c-a942-63ccdbb3a9ee
