Subject: [PATCH 28/30] Let finding install classes be more flexible for Fedora
 (#1155452).

Related: rhbz#1155452

(1) Make it so a valid install class does not have to be named "InstallClass"
which should make inheritance less cumbersome.

(2) Allow putting more than one install class into a single file.

(3) Rename the existing install classes to be <distro>BaseInstallClass.  This
makes it more clear for subclasses where they're coming from.

Port of commit 8c2550d20d7fd8964cd3ec5797ff34949fe0f8fd from master.
