Create function `Database->getNativeFormElements()` to unify all needed actions on fresh loaded FormElements like explodeParameterInArrayElements, duplicateRetypEelements, copyAttributesToFormElements. Native FormElements will be loaded on 4 different places in 3 classes.

HelperFormElement.php: Moved copyAttributesToFormElements() from QuickFormQuery to HelperFormElement.
AbstractBuildForm.php, BuildFormBootstrap.php, QuickFormQuery.php : Use of Database->getNativeFormElements()
Database.php: HelperFormElement::copyAttributesToFormElements()

FormAction.phhp, Store.php, AbstractBuildForm.php, Constants.php, QuickForemQuery.php, Index.rst: Added STORE_BEFORE, #3146

FormAction.php, Report.php, Sendmail.php, Index.rst:  By default all QFQ send mails contains now 'auto-submit'.

Form.js: When boostrap-validator is available use it to validate forms, instead of blindly using .checkValidity() on. Allows to detect errors recognized only by bootstrap-validator.

AbstractBuildForm.php, QuickFormQuery.php: Added specific validator.js error text definition to remaining HTML form elements. Not sure if all of them will benefit of it.

Added validator.js attributes 'data-pattern-error', 'data-rquired-error', 'data-match-error', 'data-error' to be specified in config.qfq.ini, Form or FormElement. Detailed setting will overwrite generic setting. If none is specified, take validator.js defaults.

HelperFormElement.php, AbstractBuildForm.php, Constants.php, QuickFormQuery.php.

HelperFormElement.php, AbstractBuildForm.php, Constants.php: 'Retype function' - default value will be copied to second element. Detection of secondary-'retype'-FormElement can be done by isset($fe[FE_RETYPE_SOURCE_NAME])  .

AbstractBuildForm.php: added new 'data-compare-element' for buildInput().
QuickFormQuery.php: Adjsut native FormElements in case some of them are 'retype=1'

Logger.php, BuildFormBootstrap.php, BuildFormPlain.php, BuildFormTable.php, Constants.php, BuildFormPlainTest.php: Replace 'label' and 'note' for FormElements by FE_LABEL, FE_NOTE.

Index.rst: Update documentation foer 'retype=1', "email, password retype input with client side equal check". Additional notes for table classes.
