Nav: Made CTRL+TAB skip menus + skip the current navigation window if is has the ImGuiWindow_NoNavFocus set. (#787) 

While it was previously possible, you won't be able to CTRL-TAB out and immediately back in a window with the ImGuiWindow_NoNavFocus flag.

- ArrowButton: Fixed to honor PushButtonRepeat() setting (and internals' ImGuiItemFlags_ButtonRepeat).
- ArrowButton: Setup current line text baseline so that ArrowButton() + SameLine() + Text() are aligned properly.
- Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. This is designed to allow CTRL+TAB between Tabs in the future. (#787)
- Nav: Added a CTRL+TAB window list and changed the highlight system accordingly. The change is motivated by upcoming Docking features. (#787)

While it was previously possible, you won't be able to CTRL-TAB out and immediately back in a window with the ImGuiWindow_NoNavFocus flag.
- Window: Allow menu and popups windows from ignoring the style.WindowMinSize values so short menus/popups are not padded. (#1909)
- Window: Added global io.OptResizeWindowsFromEdges option to enable resizing windows from their edges and from the lower-left corner. (#1495)
- Window: Collapse button shows hovering highlight + clicking and dragging on it allows to drag the window as well.
