Clarifications on Keys request for Gulp plugin

[caraya]

In the readme you mention This gulp Tenon plugin is open and free. However, access to the Tenon API must be granted by Tenon. You will need to obtain an API key to use it.

But it leaves a few questions open that are not clear from reading the repo or the readme:

• Is this API keyy part of the 30 day trial and afterwards I need to purchase the prooduct to continue using it?
• is the client released under the ISC licensed indicated on the Github repo (picked up from the package.json license field) or MIT?
