* Fix bug that always returned MIT

* Add LGPL3 to array of licenses

* Change to not prompt at all for package name

* Change to not prompt for author if acquired from vcs and moved before prompting for version

* Reduce excess indenting

* Create tools.writeContents to contain file writting functionality and use it to write the nimble file

* Create package src directory and add it to the nimble file

* Write an initial source file

* Create directory and files needed for testing

* Add package created message and change priority of nimble file creation
