Setup Casemate to follow drupal.org distribution packaging standards

Committed some changes with this commit to see if the packaging system will package the modules and libraries needed for Casemate correctly. Need to wait for the packaging system and confirm changes worked.

Changes

• See: http://drupal.org/developing/distributions/drupalorg
• Also referenced methods used by Drupal Commons and COD
• Renamed casemate_stub.make to build-casemate.make (Other distros are using these naming conventions)
• Renamed casemate.make to drupal-org.make to follow packaging requirements
• Setup drupal-org-core.make to build the proper core with patches

Title fix

• Related to this issue, I updated the make include, which pulls in Guardr projects with this commit (See #1894140: Setup Guardr to follow drupal.org distribution packaging standards)
• Created a casemate release to test d.o packaging
• Still need to wait for a build to complete to make sure that Guardr, modules, and themes are pulled into Casemate's 7x.-1.x-dev snapshot correctly

Well, the dev release wouldn't create because of the Guardr make include, even after fixing the URL in #3.

Here is what I get when I try to verify the make file locally:

drush verify-makefile drupal-org.make 
The top-level attribute 'includes' is not allowed.                                                                                                                                               [error]
The drupal.org validation check failed -- see http://drupal.org/node/1432190 for more information.  

It appears that we are not going to be able to include Guardr as a base distribution for Casemate as far as Drupal packaging is concerned. I recommend we hold off on a dev snapshot release for now. Once #1356276: Allow profiles to define a base/parent profile progresses a bit more for D7, we can include a core patch for it in Casemate and test that it works to include Guardr as a base distribution.

Will leave this open for now as we explore the options.
