Nav, Focus: Fixed ImGuiWindowFlags_NoBringToFrontOnFocus windows not being restoring focus properly after the main menu bar or last focused window is deactivated.

Docking: io.ConfigResizeWindowsFromEdges default to true in Docking branch. Moved code in BeginTabItem().

Refactor: Tweaked and improved the sectioning to facilitate grepping/moving around and applied to all files. (#2036)

Viewport: Making the code a little more sturdy (flag changes) + added descriptions. (#1542)

Nav: Removed the [Beta] tag from various descriptions of the gamepad/keyboard navigation system. Although it is not perfect and will keep being improved, it is fairly functional and used by many. (#787)

Renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + changed ImGuiIO layout.

Demo: Added a "Configuration" block to make io.ConfigFlags/io.BackendFlags more prominent.

Comments, demo

Renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete fast as IsItemDeactivatedAfterChange() is very recent). (#820, #956, #1875, #2034)

Added IsItemEdited() to query if the last item modified its value (or was pressed). This is equivalent to the bool returned by most widgets. It is useful in some situation e.g. using InputText() with ImGuiInputTextFlags_EnterReturnsTrue. (#2034)

Added optional misc/stl/imgui_stl.h wrapper to use with STL types (e.g. InputText with std::string). (#2035, #2006, #1443, #1008)
