syntax: %(argv0)s [options] project-dir-name 'Project Long Name' app-exe 'App Name'

Creates a new project with given name with everything running on a single
server.

Misc options:
   --verbose={0,1,2}  default: 1
   -v                 alias for --verbose=2
   --no_query       accept all directories without querying
   --user_name      default: $USER (%(USER)s)

Dir-options:
   --base           default: $HOME (%(HOME)s)
   --key_dir        default: BASE/keys
   --project_root   default: BASE/projects/PROJECT
   --url_base       REQUIRED; e.g.: http://maggie.ssl.berkeley.edu/

   --html_user_url  default: URL_BASE/PROJECT/
   --html_ops_url   default: URL_BASE/PROJECT_ops/
   --cgi_url        default: URL_BASE/PROJECT_cgi/

E.g. if you run make_project --base $HOME/boinc --url_base http://boink/ yah 'YETI @ Home'

Then upload_dir = $HOME/boinc/projects/yah/upload
and  cgi_url    = http://boink/yah_cgi/

By default, directory options will be queried if they do not exist yet.
