Releases for Digg this

Feature request #637288 by jasont28: added permission for administering diggthis module settings.

Several bugs fixed in the Drupal 5 branch:
-Added HTML comments around the JavaScript variables for the digg this button to avoid them from being indexed by Drupal's search system #356731;
-Limit the legth of the title and the teaser #191746;
-Unquoted title variable #292792;
-Added the $bg_string to the JS code to let the background color actually have an effect;

New Features in v2
- Added a block for display on all pages except admin
- Added a page with diggthis top stories for the domain set

Added function to cut titles and descriptions that are too long.

Added a weight feature for button display above or below the main content.

This version of the diggthis module allows to show a digg button in the full view of nodes. Admins can choose which node types to enable for display of a diggthis button, set the background color of the button and the standard or compact form of the button.
