update on ARB exception for /opt installation

[Allison Randal]

Tech Board met again today and agreed on:

- Allow .desktop files to be installed outside /opt. This is the only
exception needed, and persia has a potential workaround for Maverick.
- In Natty, we'll modify Quickly, cdbs, python-support, and related
packages to support installation in /opt.
- For Maverick, accept that .pyc files and version symlinks won't be
generated for Python libraries.
- For Maverick, ARB will perform manual package fixes on proposed
applications, to install in /opt and load libraries from /opt.
- Binaries only in /opt (no exceptions for Maverick), will not be in $PATH.
- Official install location is /opt/extras.ubuntu.com/<packagename>
(with version number, i.e. "/opt/extras.ubuntu.com/foo-1.5")
