[CWB] [CQPweb] dockerized version

[Stefan Evert]

>  I have re-inserted cwb-perl into my Docker build. However, just the cwb-perl main module is present, please advice me if the other three modules are still needed and/or maintained.

CWB-Perl contains all the extra command-line utilities and is relevant for most users.

The other modules are only relevant for Perl programmers, but all are still maintained.  The CQPDemo Web interfaces (including the Europarl search interface at http://opus.nlpl.eu/cwb/Europarl7/frames-cqp.html) require CWB-CL and CWB-Web.

Best,
Stefan
