delete, set as default.
plugins.class.php was merged back to a state it doesn't manage themes at all.
themes.class.php was created instead, from a duplication of plugins.class.php
and strongly modified then.
feature 1507: the display of available themes is now much more "graphic".

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.
