Ease installation process of the plugin
Generally, the installation process of a plugin starts from a .tar.gz, or .zip file which is first downloaded from the forge, then copied in ./glpi/plugins directory, then decompressed.
Decompression creates a directory named according to the plugin, which contains all necessary files for the plugin.
Bug moreldap.zip does not contain any directory named moreldap. It contains directly in its root directory all files. So, at the decompression step, all files are copied directly in /plugins directory !
Would be nice to provide a .zip respecting GLPI standards.
