Martin Atkins 72ad927c4d configs/configload: package for loading configurations
Previously the behavior for loading and installing modules was included in
the same package as the representation of the module tree (in the
config/module package).

In our new world, the model of a module tree (now called a "Config") is
included in "configs" along with the Module and File structs. This new
package replaces the loading and installation functionality previously
in config/module with new equivalents that work with the model objects
in "configs".

As of this commit, only the loading functionality is implemented. The
installation functionality will follow in subsequent commits.
