License Generator Interactive Mode (#23)

* Added a Key Generating script

To make the keygen process a bit easier I've added a `generate-keys.sh` script that can be found in the `.keys` directory. It will generate the key & cert and bundle them into the required pkcs#12 file.

I've updated the readme to include instructions on the script.

* Generate bitbetter/identiry container with modified Core.dll

Added the generation of a second modified container, bitbetter/identity, which contains the modified dll. Fixes #12.

This works on my testing environment but has not gone through extensive testing. I'd recommend a review and cleanup of this commit before it is merged into the develop or master branches.

* Updated Docs

I've taken the steps written out by @online-stuff and consolidated/organized them into the README. This closes #13.

In a future update it might be worth adding a docs/ directory and breaking the readme into several docs that link to one another.

* Updated build.sh

Build now checks for and creates missing .keys directories.

* Added subj to allow for non-interactive use.

* Generate keys on build.

* Circle-ci needs to gen keys to test build

* Generate keys if they don't exist.

Don't overwrite if keys already exist.

* Generate keys online in the .keys directory

* Updated README.md

* Added initial interactive options

* Functional implementation of licensegen interactive mode.

* Bumped Newtonson.Json version

Never versions of the dotnet-sdk have issues with older Newtonsoft versions. 12.0.1 seems to satisfy the widest variety of sdk versions.

* Removing old readme

* Removed Duplicate Section

* Fixed typo

This fixes and closes issue #24.
