Refactor to use form.restMethod instead of form.permNew|edit=rest. Next step will be to eliminate formMode=FORM_REST

Refs #7634. Refactor. REST form/id's are now in STORE_CLIENT. Unit Tests will fail - not updated to new function.

Refs #7634. Session Timeout zu kurz. Add logout of FE user. Logout happens not directly on the first call, but on the second or third page access.

B7634. Fixes #7634. Session Timeout zu kurz. The bug was probably not a bug, but a too short timeout together with an misleading exception (logout and in - but reload the page also leads to valid page). The fix is 'take the system default (php.ini) and set that one'.

Fixes #7864. 'required'-FE Elements, deactivated via formModeGlobal=requiredOff, now gets class 'required-field'. The final 'required' mode is still temporarily disabled.

Fixes #6914. Final implemention of customized typeMessageViolation. Incl. unit tests. New escape mode 'C' - escapes ':' by '\'.' - useful for variables in variable definition.

Refs #7743. Move error mesages to Constants.php. Unit tests use those constants now. 'data-pattern-error' only delivered if a 'pattern' is given. 'required' attribute only delivered is set.

Refs #7743. Detection of 'pattern error' on per QFQ default, custom instance wide, per form or per FormElement - per FormElement overwrites other. System specific generated overwrites QFQ static default, instance wide default. Move default pattern to constants.

Refs #7743. Add unit tests. Make default error text more specific (only if default error text is not explicit set in config, form or form-element)

Fixes #7620. Label align left/center/right. Defined by config/form/formelement. FormEditor slightly redesigned.

Fixes #7594: FE.type=extra: don't name it 'type' or 'id' or 'L' - more detailed error message and an explanation in Manual.rst.

Bug 7539: Copy to clipboard not reliable. This commit fixes problems with 'copy file content' to clipboard. Refs #7539

Refactor: Manual.rst update config variables (reorder), add 'qfqLog'. Support.php: formSubmitLog hardcoded to fileadmin/protected/log. DOCUMENTATION_QFQ > SYSTEM_DOCUMENTATION_QFQ. Remove config var 'logDir'.
