Feature #4720 - Implemented select-list with dbIndexList as FE.parameter option. Works, but is unflexible. Looking for a better solution.

Makefile: fixed unwanted removing of whole 'doc' by 'maintainer-clean' - doc nowadays contains QFQ related manually created documentation.

Makefile: change installation of phpDocumentor to --alldeps and remove 'phpdoc/'.

allow concurrent builds.

Makefile: qfq-doc
setVersion.sh: rename Setting.yml to Setting.cfg

Run sphinx before rolling ZIP files.

Fixed plantuml download URL.

Makefile: `make archive` now generates again an extention which can be installed in T3 6.2 and 7.6. The problem was that the zip filename has to be equal to the extension name.

Changed Makefile: please do

  rm -f .bowerpackages .doc_plantuml .npmpackages \
   .phpdocinstall .plantuml .support .support_plantuml
  rm -rf doc
  make bootstrap
