Update the About Spec

[chinyeungli]

Suggested update:

dje_license: The DejaCode Enterprise license URNs, license name or license key for the component.

It's too generic. we should have:
dje_license_name
dje_license_key
dje_license_urn

AND we should support a composition a multiple licenses in About

Wrong commit, I meant fixed #122 not this one.

The Spec needs to be reviewed and to be updated to match with the current code.
