Better Test support

[alejandro_wille]

Convert some of your entities to interfaces to allow DI to swap them out. For instance, now I have:
interface IRecord
{
...
public void setAttribute(String property, String value);

public String getAttribute(String property);
...
}

and then I have RecordEx extends Record implements IRecord

and on the server/for my test cases, I can have RecordImpl implements IRecord. (and it's really just a map)

Now I am able to test more without using Selenium or GWTTest case, or other such frameworks, and I am able to leverage the speed and functionality of test frameworks that don't require a browser.

It would be nice if some of this was supported natively.
