Nah, these dummy classes would turn out quite complex anyway. Better
to just use ifdefs elsewhere, the number required is not that large.
This reverts commit 6d33801b4498f5c13d2dc75588f88c22a11f455b.
Work in progress, the dummy class implementations surely still
incomplete and/or might contain methods not actually needed. More
dummy class implementations needed, hopefully not too many
though. Will add also a few ifdefs for DISABLE_SCRIPTING in some key
places in sc and elsewhere to cut down on the need.
Any LO-based app distributed through the App Store can't have
scripting or extendability anyway.
Sure, this will break the build elsewhere because of missing headers.
No big deal, I will take care of that eventually. It isn't as if there
would anybody else building for iOS anyway, as far as I know. If there
is, please make yourself heard.
