Return Date objects from any Angular SDK resource that has a date property

[scalarsys]

I took a try at #141 "Auto-convert timestamp/date string attributes to Date objects" using an example provided by @xak2000

Gist of Example

My contribution extends the services template to include the dateTransformer factory from the example. The template then conditionally injects the dateTransformer and adds a transformResponse to each resource that has at least one property that is defined as a date, passing the property name(s) to the transformer.

Concerns:

• Should there be a switch on the generator or some other backwards compatibility approach
• Introduces a requirement for lbServices consumers to have lodash and moment
• Is this the best way to get and array of property definition from within the template meta.sharedClass.ctor.definition.rawProperties

On the CLA page it just shows the "You have signed this CLA" button, I have tried signing out and back in as well as clicking through each of the two agreements shown in the agreements list, both show the same.

I had used a different github account to commit the changes to this PR and that is why the CLA check was failing, fixed now. Let me know, regarding any next steps.

Would really like to see this happen. Would prevent a lot of manual transforms. @scalarsys do you need help with getting the checks fixed?

I removed my old fork and re-did the changes against the latest master, couple failing tests still over @ My Fork

Can't work on it anymore this weekend so wanted to push up what I have.

This pull request seems rather abandoned to me. If there is anybody willing to take over the work, then please open a new pull request and mention my GH handle in the PR description.
