Prevent "Wrap in ref."
btw:none is now properly automatically added.

Previously, when btw:contrastive-section was created in a document,
btw:none was not automatically inserted in the empty child
elements. This was a regression bug, now fixed.
Allow more contents in btw:cit, btw:tr, etc.

btw:cit and btw:tr (and foreign when it appears there) now accept all
the various emphases (antonym, congate, conceptual proximate, lemma), everywhere.
Change to make bash complete targets more nicely.
Create a tunnel automatically.
Fixed the warning about duplicate entries.

Previously, a unicode character showing up in the lemma would prevent
creating the message. This has been fixed.
Be generous with the timeouts.
Use the minified version of DataTables.
Required wed version upgrade.
