addthis 6.x-2.0-beta

A rewrite of the module including some new features:

1) Username is no longer fixed and can be changed trough administration.
2) There is now administration section for full control over how the button is displayed.
3) Module now implements hook_block to create a block for the button. Visibility of this block can be controlled as usual so the button can be limited by content type, taxonomy or what ever you want.
4) Module also implements hook_nodeapi and AddThis button can be used in a theme with: print $node->content['addthis']['#value'];
5) There are now two permissions for the module: one for viewing the button and one for administration.

This release is still beta and is not recommended for production environments.
