Move screendump from apps to firmware, solving two nasty firmware-to-apps calls. This required to move the filename creation functions as well. * Fix bug in the BMP header of Clip screendumps. * Add remote screendump for targets with an LCD remote. * Simplify some ifdefs and rename a macro in the sim.
