[sharing] http control of a panasonic projector

because pjlink doesn't allow a lot of manipulation,
i made this patch to acces a projector's menu via http (in order to control the matrix position of a panasonic videoprojector )

you can acces to the projector's menu and make automatisation with osd_off if you would like to change parameters dynamically in live
( for example it was uselfull to change the covery of a dual projection on several plane on the scene with 2 vp)

doesn't work on windows because the activeX control not refresh the http interface more than one time (on that state of the research)
