Remove the '1.0' in the #%Module magic cookie header of the generated
initrc configuration file. Users may define a more appropriate magic
cookie compatibility version.
When the installation option `--enable-modulespath` is set, the list of
modulepath to enable by default is now only defined in the `modulespath`
configuration file and not anymore in the `initrc` configuration file.
Add example code in default initrc, the initialization script of
Modules, to either restore user's default collection if it exists or
load a predefined module list when initializating Modules.
Rename the configuration template files following the new default naming
scheme for these files: modulerc becomes initrc and .modulespath becomes
modulespath.
