Change Create Project from Template to use new evidence.templateProjectUrl setting

[RandomFractals]

to allow users to use their local file:// template projects when creating new Evidence project from a template that was added in #2.

• Instead of using default Evidence template project GithHub repository Url, change it to read user preferences from Evidence extension settings, and display that setting value in the Create Project from Template template Url input box
• Use local template folder support added in Use new simple Evidence /template bundled with extension to create New Project #61 to project.ts to create projects from local templates
• Change Template Project GitHub Url input box and other messages from Start Server and Create project from template progress notification messages and display #57 as needed

I suggest we leave this out of v1.1.0 release (#65) and revisit consolidating New Evidence Project and Create Project from Template into one if we want to support the built-in /template from extension and local file:// project template folders in this workflow.

So, for now this command will always prompt for and validate if a user entered a GitHub Url for the template to use and clone template repo to start new Evidence project using this template.

will be reviewed and consolidated in future sprints after v1.1.0 release.
