Client-side: Select components

[Jani Laakso]

TODOS (not only client side stuff):

• server gives two options for "null-selections" and other null selection issues. Old 4.x era ticket for this: #574
• extend default select and in constructor to put it into proper state for twincol, multitselect, optiongroup. Avoid using style in uidl to select proper client side component.
• decide how selects should layout themselves (expand to use whole width or only the size that options take)
  • setColumns() (to match textfield) for Nativeselect, Listselect, (Twincolselect?), Select, Combobox
  • setRows() for Listselect, Twincolselect

When navigating a normal select component with arrow keys and there are more items available than can fit in to the screen, the popup doesn't scroll when the user moves the selection out of the popup.

I'll split todos above into separate tickets
