Updated packaging scripts for cygwin.

Completed migration from buildbot scripts that are PyLith specific to
packaging scripts in source distribution that are run manually at
release time.
Merge branch 'baagaard/fix-packaging'

* baagaard/fix-packaging:
  Updated packaging scripts for cygwin.
Small fix to manual.
Small fix to table caption (move to body text).
Update sizing function calls to work on all volumes.

Previous version of journal script imported the sizing function one
volume at a time by looping over volumes. This causes CUBIT 14.0 and
14.1 to crash. Switching to importing over all volumes is faster and
prevents the crashes. This also seems to be ok in CUBIT 13.2.

* baagaard/fix-cubit-cellsize:
