Unstable version 2.2.0 beta 2 released

Keeping with a bi-weekly unstable release schedule and syncing releases with the 2.1.x branch, we release the second beta of the next major update to Exponent, v2.2.0 (beta 2).  In addition to fixing many issues (including those fixed in v2.1.4), we've tweaked and updated the online donations and event registration modules.  We also now make greater use of ajax paging and the new html5 input types.  There is also a new forms 'portfolio' view to display a multi-item custom view of form data.  This also marks the transition to move the 'develop' code branch to the 2.2.0 line code as of 1 Apr 2013 (this is NOT an April Fools Joke)
