Added ProfileInstaller::removeUnderscores.

  Now supports project names with underscores, e.g.
  - project name: my_project
  - valid class names: MyProject, MyProjectSubprofile
  - valid class files: MyProject.php, MyProjectSubprofile.php
Added copy of standard core's profile to be refactored as example.

  Rename standard -> standard2.

 	new file:   examples/baseprofiles/standard2
Moved work-in-progress example profile into example/baseprofiles directory.
Fixed misc bugs to get draft code working for real installs.
