[PD-767] Used SFM widget for seo sites.
Implemented Ashley's suggestions.
Removed init method as it didn't seem to be doing anything productive.
I *think* I fixed job source ids
Removed lazy option as it's redundant.
Moved to lazy loading
updated searchable fields and lazily load widgets.
moved job source ids stuff to company form as not everything that inherits from seositereverse needs it.
Separate email sending from save
Only unverify on block/drop [PD-809]
Merge branch 'master' into prm-always-send
Update SavedSearch last sent when sending as part of a SavedSearchDigest [PD-818]
Removed limiting by frequency from saved search emails and forced partner saved search emails to send even if there are no search results
Saved search digests should also send no matter what for partner saved searches [PD-820]
More tests for searches with no jobs [PD-820]
Merge pull request #1043 from DirectEmployers/spamreport-stay-verified

Only unverify on block/drop [PD-809]
Made the very bad if statement worse by also checking to make sure we shouldn't just ignore dates for jobs
Combine initial saved search and invitation emails, remove reserve check [PD-799]
modified initial data.
Rolled back to using the slow widget for the moment.
