Improve conj.

* data/dbverb.struct: Use utf8_bin collation for the `verb' column in
all tables.
* data/irregular-verbs.xml: Update.
* po/POTFILES.in: Add conj.scm4.
* po/pl.po: Update.
* src/cgi-bin/conj.scm4: Try to fix some common input errors.
Look up the verb in the dictionary. If there are no tones in
the input word, look it up in the dictionary using the "soundslike"
method.
* style.css: Add h2.verb class.
