Choco New Command should support Templates

[JPRuskin]

Expected Behavior

We currently support the basic choco new, but we should support the ability to specify a template.

Current Behavior

We can only produce the default package.

Possible Solution

If there is one template available, it should be used. If there are more, we should prompt for a choice - perhaps having a setting to allow a default option.

Context

I use templates sometimes. I can't currently use templates within the extension.
