* 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 automatically when running the build script if none already exist.
* 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.
