rules 7.x-2.0-beta1

Development status:
The module is fully functional now and has a basically working upgrade path. See the README for instructions on how to upgrade your rules from Drupal 6.

Changes since 7.x-2.0-alpha5:

• #997474 added rules 1.x to 2.x conversion support and API for contributed modules. Converting rules basically works, but needs more testing. Taxonomy integration conversion is incomplete.
• Added README content like instructions for installation and documentation links
• #1068168 patch by klausi: Auto saving of a new node after the event node_insert is broken
• #1058756 patch by sepgil: data selector popup cannot be closed
• #1074262 patch by TR: Incorrect logic in RulesDataUI::renderOptionsLabel()
• #1083908 fixed reaction rule weight to be actually applied.
• #1072550 patch by klausi: Support saving and deletion for the generic entity type.
• #1083662 patch by das-peter: Invalid arguments for creating a new RulesException in modules/rules_core.eval.inc.
