Add Chrome/Linux support for the Developer Plugin.  Note that this does not support asking the user to allow non-localhost connections or storing that whitelist, and Mac support will be added later though much of the Makefile work is also relevant there.  Also, the MissingPlugins page is not updated in this patch because we want to get more mileage on this before giving it out to everyone, and we should probably fix non-localhost connections first as well.
