Incorrect or missing SVN property settings

There are quite a few incorrect SVN property settings.

A lot of files have been flagged as executable; this is generally a bad idea in SVN.
If files do need to be executable, that should be done as part of the release process (anyway the exec bit is not preserved by Zip archives)

A lot of source files don't have eol-style = native.
This tends to cause problems when committers work on different OSes.

Patches to follow - can be applied on Unix or Windows (rename the script file).
