Describe the bug

Support for the output theme license. Right now it is leveraging the nvQuickTheme LICENSE file, but that is obviously not acceptable for everyone and that is inappropriately mixing the nvQuickTheme licensing with the custom theme (output) license, which is used during the DNN installation process to display the license for the theme being installed. These are two different licenses altogether. One is for the tool (nvQuickTheme) and the other is for the custom theme install package.

To Reproduce

Run gulp package. During installation of the output theme package into a DNN instance, you will see the contents of the LICENSE file on the installation step that shows the theme license.

Expected behavior

The license information shown during the theme installation should be custom to the theme install package being created.
