Add App > Get with File: full app backup zip from the device

Reads app.sab and kits.scode over Sox file transfer, decodes app.sab to
app.sax (byte-identical to sedonac), and on Orion/Rion also fetches the
images and fonts the app names, with their sources from Sedona home's
banks. Offers to save the app on the device first when it is dirty, and
asks where to save with <Sedona home>/store/apps and
app-<device>-<app>-<timestamp>.zip filled in.

DASP trace lines are now printed by their own thread: printing from the
network threads to an unread stdout pipe blocked the receiver and made
file transfers time out.
