Give ability to change the default get separator

[gallofeliz]

Hi,

As it is possible to use "_" for env() and argv() (or '-'), it should be good te be able to configure the get separator.

Example :

{
    "database": {
        "user": "root"
    }
}

I would like to get database:user doing nconf.get('database.user'). It's more natural.

I think this is actually a bug, because it seems like it's supported, but isn't actually honored.

PR created (#307), but will be held until we're ready to bump the major version (hopefully later this year), since it's a potentially breaking API change.

Ok, good !

This is fixed/changed via #337 and will be released as part of v1.0.0.
