Gwenhywfar

GUI: Dont ask for TAN in non-interactive mode (fixes #129).

Set dylib extension for cmake files on macOS

Require only QtCore QtGui and QtWidgets

This makes possible to build gwenhywfar on systems that don't have e.g.
QtQml compiled.

Fix mingw compiler error about mismatching declaration

xmlcmd: LibXML2 version of toDb finished but yet untested.

Started adding an XMLCMD implementation using libxml2.

Merge branch 'mp-202004-xmlcmd'

Added module xmlcmd.

Fixed a bug in new code.

More generic approach to using XML as command language.

Internally xml2db already was a generic approach but the API wasn't
exposed so far.

Now this can also be used to write other XML-driven parsers.

Result of "make format".
