#24 blosxom 2.1.0 breaks "uselib" plugin

[Martin]

The changes in 2.1.0 in relation to the loading of plugins breaks the uselib plugin.

This is because blosxom now does
unshift @INC, @plugin_dirs;
before loading all the plugins, and then follows it up with
shift @INC foreach @plugin_dirs;

However, with the uselib plugin adding a path to the beginning of @INC, this is subsequently removed by the "shift".

Will have a look at it.
