[Plugin: GravatarLocalCache] problems with the plugin

found some issues:

1. You use GravatarLocalCache a lot but the folder name is gravatarlocalcache and this confuses wordpress installations that use Linux.
2. It doesn’t seem to work, its either my theme: hybrid theme or the W3 Total Cache even though I have emptied the cache. To be honest I guess its this plugin as its own cache folder stays empty…
