Ubuntu and Debian related strings in epiphany-browser

There are various Ubuntu and Debian related string in the epiphany browser package.

User-agent string: "Ubuntu/10.04 LTS".

The homepage is set to debian.org.

Ubuntu related search string for google: "..search?client=ubuntu&.."
Can be fixed in epiphany-browser-2.30.2/debian/epiphany-browser-data.gconf-defaults. Also it can be removed it is missing in Debian.

There is also a patch that sets a smart bookmark for google again with "client=ubuntu"
Can be fixed in epiphany-browser-2.30.2/debian/patches/80_ubuntu_search_url.patch

There are also several debian related default bookmarks.

I was going to make some patches against the source package and attach them here, but then I decided that a package helper is a better idea. I could help with this but I am absolutely unaware where to start.
