Launches a url as a web application. This script relys on the 'launch' script. This
essentially just generates the pattern and launch command to pass into that script.

USAGE:

  $ $THIS [OPTIONS] <url> [ARGS...]

OPTIONS:

  -f | --or-focus:         If a window exists matching the url's domain, focus it 
                           instead of launching new window.
  -s | --special <name>:   Launch in the special workspace name, or toggle the special 
                           workspace.
  -h | --help:             Show this help page.

NOTES:

Any extra arguments after '--' get passed directly to the browser invocation.
  
  $ launch-webapp https://example.com -- --some-random-flag-for-browser=1

Any options passed in prior to the '--' get sent to the 'launch-or' script, so you can pass
options that are not specifically shown here, but the ones shown would be the most commonly
used, so they are documented here.

Using the '--special' flag is useful for apps that you want to have a "summoning" like behavior. 
Upon first launch the application will be opened and the special workspace will be shown.  
Calling it again will keep the application open in the special workspace but hide the workspace.
Further calls will not open another instance of the application, but will toggle the visiblity
of the special workspace.
