create-spectacle: Overwriting for onepage vs t/jsx. #1199
Description
A onepage project ends up in a file foobar.html, whereas the jsx/tsx project ends up in foobar/.
If user provides a project name foobar and foobar/ directory already exists, we prompt them regarding overwriting the directory. However, if the foobar/ directory already exists, but the user selects a onepage project, then we don't necessarily need to overwrite anything.
We should make the overwrite option more flexible based on the type of project. We likely need to prompt the user for type of project prior to asking for the name, so we can do a dynamic overwrite check based on type of project.
