[IMP] : change default DateTime Format for just date + hour/min. seconds are removed. can always be customized by the used in custom config file

[RFR] : removes some unused vars
[IMP] : improvement, now opening a directory need a double click like on all systems. a simple click on a directory outside of 'directory chooser mode', will not select the directory
[FIX] : fix possible buffer overflow in a variadic item
