B13716: Added font license documentation. Created new folder for custom_fonts and implemented copy function in gruntfile. refs #13716

B13716: Added new font file in extension for password. And changed path from remote to local font file.

F12630: Extended compatibility with user given time format. Format HH:mm:ss activates field showSeconds. Record lock function for changing seconds and correctly shown arrows for seconds implemented.

B13767 this fix prevents marking elements with class .btn to required color, which aren't given from forms itself (all form buttons are 'button' tags). In this case we need to filter out anchor tags with blank href (#) (sometimes used as buttons from other js frameworks like datetimepicker to trigger some functions). Also implemented new CSS lines to overwrite specific bootstrap.css rules for the datetimepicker (arrows are higher positioned, which looks better than before)

S13827: Added new font family to fake passwords. Using the font for formelement password. At the end we dont use the input type password anymore. Best solution to prevent offers of user credentials from browser.

B13084 Dropdown menue is now clickable on smartphone. z-index is set higher than from dropdown-backdrop class

Button is seperated in own div with class row and col-md-12. Now it will be rendered after closing the form-tag.
