Add CherryPy dependency and minimal install info to doc/install.txt.

I seem to have left CherryPy out of the earlier list.

The extra handholding for minimal installations is an attempt to
address problems people have had installing BE on non-Linux systems,
where the standard build tools are less common.

I also mention my Gentoo overlay and Michel Alexandre Salim's Fedora
package, so people running Gentoo and Fedora don't have to bother
figuring any of this out ;).

Finally, I moved the package information up to the top of the install
page, so people on supported systems realize they have an easy out
before reading through the install procedure.

 Installing BE
 *************
 
+Distribution packages
+=====================
+
+Some distributions (Debian_ , Ubuntu_ , others?) package BE.  If
+you're running one of those distributions, you can install the package
+with your regular package manager.  For Debian, Ubuntu, and related
+distros, that's::
+
+    $ apt-get install bugs-everywhere
+
+However, the official packages can lag behind current development.
+
+If you're running Gentoo_, I've got a live ebuild in my overlay_ that
+installs the current version of BE from the Git source.
+
+Michel Alexandre Salim maintains a Fedora_ package.
