Add a second between ingested assets to compensate for transcoding expansion
Fixup slot_asset durations after transcoding
Add media.AV.frame option to rescale, and always use SAR

Rescaling is yet unused

Manually constrain all video frames to 480px for now

See #1039

Beef up typeService segment handling

full).  Submission of singletons is still an issue, however.
Fix SlotAsset.getAsset harder

Fix #1822

Slot.rowVolume(volume) and all the other calls on Slot should be

With AuthForm, require the current user's password, not target

Only relevant with superuser.  Nasty casts.

formerly incorrect) UI behavior.
Unangularize /party/create

Fix #1821

I remember  that horrid cast line.  Turns out it shouldn't've be quite

Also added url, why not, see #1823
Shrink thumbs of cached frames, too

Really the most important ones anyway
