Release Candidate 1 - v2.2.0 Set Loose

In what is hoped to be the final unstable release before v2.2.0 is released as stable, we present v2.2.0release-candidate1.  This version contains the final feature additions prior to the release of a stable version, no features will be added until after that release.  This version marks the return to naming the new container 2.0 controller simply 'container' instead of container2.  It also adds a new sample e-Commerce store database available during installation; and many enhancements to the online donations and event registrations modules including the new option of single or multi-person registration using site forms to collect data.
