CRM-13235

----------------------------------------
* CRM-13235: Custom event name badges cannot be created as extensions
  http://issues.civicrm.org/jira/browse/CRM-13235
Set class to disabled for contact summary tabs which have 0 items in them.
Change Birth date labels to Birth Date to match title case used in other labels.
CRMDOC - Change various CRMDOCxx links to plain CRMDOC

Most of the source comments with documentation links should reflect current version.

For the "incremental upgrade" messages, I left the CRMDOCxx URLs in tact
because these messages could actually be version specific.
