fix(project-template): set baseDir to '.wwwroot' for ASP.NET Core pro…

…jects

Add new baseDir property in aurelia.json with default value of '.'.
Override baseDir value to './wwwroot' for ASP.NET Core projects.

Also allows baseDir to be configurable via aurelia.json instead of
having to change the hard-code value in run.js/ts.
