Add a few fixes to the dictionary source

A large part is derived from a diff between 0.48 and Debian's 0.48.5.

Also,
- split the sed script into one to be executed initially and another one
  after webfilter.
- Use Debian's 0.48.5 instead of 0.48.4 (does not change much).
- Correctly set the version of the dictionary (as written by `dict -D').
- Do not patch the Makefile but execute the commands directly.
- Simplify prepare() and build().
- Add a check function.
