Corrected filenames used for logging output of zip commands.

Zips binaries into three zips rather than one, to make them easier to download.

Simplified the locations of some generated files, so they are created where they need to be rather than created on one place and moved to another. Zipping of binaries now assumes that there's always an rnd exclude file, as it is always created by populateziptemplate.pl, even if there's nothing put into it.
