Scribe2 1.2 "JP2-foldout-patchwork"

hi All,

we've checked in a new rev of the scribe2 codebase that
has been merged into the petabox tree. any subsequent
pushouts to scribenodes will include code that is loosely
considered version 1.2 of the scribe2 software. for scribes
with this code, you will see the following version info
at the bottom of the biblio search or image page(s):

   Scribe2 v1.2

NOTE: although initial engineering tests have demonstrated
basic functionality, it has yet to be thoroughly tested
in the field (or at all really), so we expect to uncover
new bugs, but *hopefully* this update makes things better.

this update includes:

  Scribe2 v1.2
  - improved JP2 error-handling (RETRY)
  - foldout Reshoot w/JP2 processing
  - Insert w/JP2 processing
  - foldout PPI input

notes:

- improved JP2 error-handling (RETRY).

  when there is any JP2 processing happening, the user
  will be prompted to "Please retry" until all JP2 procs,
  and proc_files have gone away. this check occurs in the
  image loop on "reshoot" and on "finish", and in both
  non-foldout and foldout mode RePublisher reshoot and
  insert; hopefully preventing JP2 processing collisions.
  there is still a zero-length JP2 error-check, but
  should no longer result in marking of bad JP2s to be
  reshot in RePublisher.

- foldout Reshoot w/JP2 processing.

  reshoot in non-foldout and foldout RePublisher now
  checks for existing JP2 processing before allowing
  the user to proceed, and processes subsequent JP2s
  inline (which means the interface blocks until all
  JP2 processing has finished - a single reshoot or
  insert can take several minutes). previously, it was
  possible to cause JP2 errors by reshooting the same
  spread.

- Insert w/JP2 processing.

  inserting spreads should now work for scribes doing
  JP2 compress (i.e. all scribes) in non-foldout and
  foldout mode. until now, only the non-JP2 codepath
  was available, so inserting prior to this just deleted
  spreads and broke the book.

- foldout PPI input.

  a dialog box now appears on reshoot or insert in
  RePublisher in foldout mode for the user to input
  the PPI based on the camera lens height from the page.
  please see the related booksgroup thread on foldout
  ppi input.

thanks so much for everyone's help in providing this update!
