Building a stable version off of whats been in dev for months

Bug fixes

• #1599386: Somes changes to facilate cloning content nodes post-clone
• #1423000: spaces_og_form_group_submit needs to be purged

Additional Considerations

• This is the first full d.o. publish of a stable release but is starting at alpha3 because of previously released versions marked a1 and a2 on an offsite fserver
