Since cygwin bash scripts need a cygwin-syntax path to autobuild, convert to a
local 'autobuild' variable using shell_path.
Remove kludges in other languages involving cygdrive twiddling.

changes for additional packages to be packaged from the same build. see BuildParams for example environment variables used to specify the packages and their channels and sourceids. also updated mac packages to use a larger virtual drive and auto-open on download

Updated llappearance-utility-source autobuild package to latest and changed debian changelog mangling to include codeticket number.
