#90: Added common_license list so that a user can input a list of common
licenses which would be displayed at the end of the attribution file.
Licenses not present in this list will be displayed inline with the
component.
Fixed #89 to handle duplicated keys in the input.
update the wording from "doesn't" to "does not"
Added test cases/code for #89
Added a function to get the dje_license name from the provided dje_license_key, and then the tool will replace/create the 'dje_license' with the dje_license name

Note that this code is ugly. This is just a temp fix and it needs to be update/modifiy.
Merge branch 'develop' into 86_genattrib_text_update
