Add HttpListener implementation

[zgramana]

Need to implement the HttpListener capabilities to support PhoneGap and peer-to-peer functionality in the .NET version.

Acceptance Criteria:

• Fully interoperable with listeners from CBL.iOS and CBL.Android.
• Works in all target platforms.
• Can handle multiple concurrent requests.
• (optional) OWIN-compliance

Notes:

• Dependency on Add Router support #83

@zgramana if I have 2 apps loaded on an android device is it possible to use the httplistener for the apps to talk to one another without a network connection or is this pure http/s?

[zgramana]

Yes, you should be able to do this via localhost. If you can't, it's a bug.

@zgramana Great! Where would I find the documentation specific to this, i.e. which article/s under http://developer.couchbase.com/mobile/develop...? I don't quiet understand how this would be achieved. Any help/point in the right direction would be much appreciated.
