Mongo driver upgraded to 3.0.4

All the test cases are passing now, except for one - test displayTreeWithASimpleArray in MongoResultPanelTest. This one attempts to create a MongoResult object with an array. Does mongo ever return an array to any query?

My update to MongoResult class only accepts Document objects. In your test there, you're looking to load strings into the MongoResult object.

Thanks for your pull request. I will integrate it ASAP

Regarding the Unit Test that fails, I had a look on it and it seems it is not relevant anymore. I will remove it.
