make default config path configureable

[green3g]

In app.js you can do something like this:

var app = new App({
    configPath: 'myConfig/path',
    defaultConfig: 'explorerApp'
});

Rather than having to write a custom mixin just to change the path to the config folder.

I can perhaps see the value of wanting to change the config file name to something other than viewer.js

For the config path, why wouldn't you just change that in the packages array up at the top of app.js? Doesn't that accomplish the same thing?

Yep, that would work, I didn't think about that method
