Package search improvements

[Carlos Izquierdo <gheesh@ertis.net>]

	I've noticed that the "Search package directories" engine, located at 
http://www.debian.org/distrib/packages, returns only results for the i386 
architecture. Would it be possible to include an architecture drop-down list 
just like the one that "Search the contents of packages" has?

	Also, clicking on certain PPC-specific packages using this later tool 
returns a 404 Error (e.g.: searching for quik, the main executable in package 
quik - Mac Linux Loader-, returns a link to base/quik at 
http://packages.debian.org/stable/base/quik.html, which doesn't exist).
