[TASK] Move buttons in user setting into advanced functions

The buttons "clear configuration" and "reset
temporary data" are advanced functions and should
therefore be moved to the advanced tab.

Additionally the buttons divert the attention, so that
it is very hard to notice the save button on the
top.

The patch moves the buttons to the advanced tab and
additionally aligns the select box(es) with the
input and button fields.
