cdn 6.x-2.0-beta5

The goal for 2.0 is simple: make the CDN integration module kick ass. This will be done in three ways:

1. significant expansion of functionality
2. ✓ awesome UI
3. excellent documentation, including high-quality screencasts

IMPORTANT NOTE:
The Drupal core patch has changed in beta 3 (not in this beta)! So, before updating, revert the patch of beta 2. Then update the code. Then apply the new patch.

Changes since DRUPAL-6--2-0-BETA4:

• #899438 by martinjbaker: Incorrect path in README file
• #862880 by chrism2671 and wimleers: ImageCache + Varnish + Push CDN causes problems
• Follow-up fix for an edge case in #839282 by jcmarco: Problems with shipped files and Drupal 6 file_create_url() behavior
