Fixed a bug allowing to move a _NoMove window from a child that doesn't have the flag. (#1381) ...

broken by e56eba4 (#1337)

Popups: popups can be closed with a right-click anywhere, without altering focus under the popup.(~#439)

Popups: Fixed a bug introduced in 1a35766 which made the BeginPopupContextXXX functions create popups without border. (nb: all that border mess is going away in styling clean up)

Refactor EndFrame() code that process focusing window with left mouse button. This commit should be no-op.

Demos: Tweaks of popups/context/menus section.

IO: reordering some supposedly private fields.

CollapsingHeader(bool*) variant: fixed for IsItemHovered() to work properly in the nav branch.Basically the close button now has to use ItemAdd() to be navable into, which overwrite the IsItemHovered data. (#600, #787)

Capture/release window in DX9 implementation ...

This helps a lot when the user drags a slider but carries the cursor offscreen before releasing the button - without the capturing, the slider will "stick" to the mouse cursor even after the button has been released. (This should generally be added to all Windows implementations - I won't mind doing it if you think it's a good idea.)

BeginPopupContextItem() now supports a NULL string identifier and uses the last item ID if available. For interactive items (that have an ID) this works! For non interactive items we assert.

Fix IsItemHovered() issue on child by temporarily reverting 344d48b. This is not the ideal solution. (Fix #1370)

Nav: InputTextMultiline: Fixed navigation/selection. Disabled selecting all when activating a multi-line text editor. (#787)
