raring uploads redirected to raring-proposed by default

[Colin Watson]

As I described in
https://lists.ubuntu.com/archives/ubuntu-devel/2012-October/036043.html,
all uploads to raring will now be automatically redirected to
raring-proposed by default.  They will be automatically copied to raring
once they pass various tests such as being no less installable than the
previous version, and soon I hope to take autopkgtest results into
consideration as well.

Attempts to copy ("sync") directly into raring will be refused.
syncpackage's default will be changed in the next ubuntu-dev-tools
upload, but in the meantime please use 'syncpackage -r raring-proposed'.

This was one of the last blockers to opening raring for general
development, so we should be able to get moving on this fairly soon.

Cheers,
