Finish changes in up/down arrows for menus

Restored single triangle for special menus, which still isn't perfect but
probably makes more sense.

Added drawflag bit flags to button, which is currently used to declare, that
button need to have up/down arrows. This is needed because it's tricky to
distinguish if button should have such arrows. For example, ID search buttons
is a simple block button which doesn't directly mean it'll have pop-up menu
and not all buttons which cases pop-up menu to display need to have such
arrows.

So currently only ID selector button is forcing up/down arrows to be displayed,
all the rest buttons now behaves in the same way as it used to be before.
