Fixed rendering checkboxes: alignment of multicheckboxes was still buggy - multi in vertical and horizontal are ok now. The labels too.
AbstractBuildForm.php, Constants.php: The checkbox is now only wrapped in a <label> element in ALIGN_VERTICAL Mode. This is identical to the radio.

Fixed rendering of ' checkbox'. formelement.parameter['orientation'] removed (replace by formelement.maxLength)
UserManual/index.rst: Doc updated for checkbox/maxlength.
AbstractBuildForm.php, Constants.php: class 'checkbox' and 'checkbox-inline' always rendered. Insert <br> where necessary.

Changed Makefile: please do

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

AbstractBuildForm.php: Class 'radio' or 'radio-inline' assigned to each individual radio element. After formelement['maxlength'] elements, a <br> is rendered.

QfqForm.js: support `required` configuration attribute.

Recode: fromelement.mode='readonly' new implemented on client, by using CSS attribute 'disabled'. The HTML atrribute 'readonly' is fine for pure 'input' elements, but does not work sufficient for 'select', 'checkbox', 'radio'. Also, the label (left of input) and note (right of input) are now grayed out if set to 'disable'.
FillStoreForm.php, Save.php: strings replaced by constants. New central function getfeMode() used by getJsonFeMode() and getAttributeFeMode()

Support for `data-hidden` and `data-disabled` attributes, which are used to initially configure form elements.

Formelement.mode='lock': removed, cause it seems that there is no difference to 'readonly'. Inside the code, there is no difference
UserManual/Index.rst: doc updated
FillStoreForm.php, Save.php: same functionality like FE_MODE_READONLY - removed.
formEditor.sql: definition updated

Support.php, FillStore.php, AbstractBuildFrom.php, BuildFormPlain.php, BuildFormTables.php, Constants.php, Save.php, BuildFormPlainTest.php

AbstractBuildForm.php Constants.php: recoded handling of '_rowClass' to be more generic, especially to add '_rowTitle' support.

QuickFormQuery.php: changed the defaults for Bootstrap forms again - look nicer on UZH CD Layout.
*.sql: Colorized subrecords for FormElements, ord will automatically computed, work on example forms (not finished)

AbstractBuildForm.php: Das Zeichen fuer Konstanten '#' war doppelt belegt. Es bedeutete auch Kommentar. Kommentare werden vor dem processing entfernt. Neu ist das Konstannten Zeichen '&'.

Bootstrap grip columns are configurable. A default on the form and, if necessary, per formelement. The default is now changed from 2,6,4 to 2,9,1
UsersManual/index.rst: updated to the new behaviour.
Support.php: setIfNotSet() has a new third parameter.
AbstractBuildForm.php, BuildFormBootstrap.php, BuildFormPlain.php, BuildFormPlain.php, QuickFormQuery.php: New abstract function fillWrapLabelInputNote().

UsersManual/index.rst: more details to 'Type: subrecord'
AbstracctBuildForm.php: check if there are no subrecords. No subrecors mean: display only the 'new' button. prepareSubrecord() returns now 'true' even if there are no subrecords.
