This effectively reverts 8c5cd962 "config split
for sdremote" (what was the rationale for that, anyway? having the two little
additions in Impress.xcs always should not be a big deal),
63a73c11 "Hopefully fix the remote config access
to work with the new schema.", ee5403b9
"officecfg: generate header for Impress-sdremote, handle "-" in xcs name", and
4cce7027 "Rename Impress-sdremote.xcs to
ImpressSdRemote.xcs + add to postprocess."
