Dev (sammyfreg#15)

* Changes to support hook

* Fix socket leak with NetImgui Server trying to reach clients
Embeded the Server Font

* Removed unused left over functions

* Warning fix on some clang build, on atomic pointer null test

* Update to Dear Imgui 1.81.  Support of NewFrame interception enabled.

* Doc update

* Update to background handling

(Server/Client) New Background command to handle custom color and texture.
(Server) BG now rendered directly in Client RenderTarget. This remove alpha blending the results into the Client Window, giving bad results on characters (alpha blending should only be used when rendering Client Imgui content, not when compositing it on top of the Server own ImGui rendering, since at that point, we don't know what alpha to use)

* Some cleanup, doc update
