fix build instructions - don't need unified.target any more when building aggregate site
parameterize create.results.html task so it can be used more generically (and copied verbatim into devstudio/product/results/build.xml); remove BUILD_ALIAS_STRING and fix comments (JBIDE-13452)
clean up template (JBIDE-13452)
JOB_NAME can include .product or .aggregate (JBIDE-13452)
because using propertyregex to override an existing variable doesn't work consistently, pass in project.version and regex it to update.site.version (JBIDE-13452)
JBIDE-13452 if STREAM_SUFFIX = _trunk, change to _master (merged in from devstudio/results/build.xml)
