Make scripts default to mediagoblin_local.ini if exists, mediagoblin.ini otherwise

[Christopher Allan Webber]

It's both hard to document and hard to follow to provide commands
where you can specify your own config file, but then you have to
specify that config file every single time for every command
afterwards.

We know people are going to write their own config files... we've
already .gitignore'd paste\_local.ini and mediagoblin\_local.ini.
When no config file is passed in, we should make it so that it
checks for and uses mediagoblin\_local.ini first and if that
doesn't exist uses mediagoblin.ini. This will allow for a simple
way for users to configure mediagoblin and be able to run commands
without accidentally running them on the wrong (non-custom) config
files, and reduce a certain amount of verbage in our docs.

Additionally we should change the paste config's reference to the
mediagoblin config file to be a list which includes
mediagoblin\_local.ini. Then we should also update the paste
factory to treat this like a list:

::

    def paste_app_factory(global_config, **app_config):
        mgoblin_app = MediaGoblinApp(app_config['config'])
    
        return mgoblin_app

Shouldn't be too hard to change that!

lazyserver should default to paste\_local also. Runtests doesn't
need to though :)

The last point is simple.
Done in branch: misc/lazyserver\_paste\_local

This also adds the ``--server-name`` option in the help's example
section, might help someone!

Updates made, including those in Elrond's branch! Merged & pushed!

Oh yeah, this is done :D
