973 PHP Web Server Action for built-in app development

- Adds the PHP Dev-Test Web Server Action to serve the application.  This has the feature of abiding by the "Quiet" flags at different levels.  I haven't seen any other built-in PHP Web Server [Yii, Laravel]. Minor feature.
- Removed "-" from CLI Text action, it was confusing
- TStdOutWriter.  This fopens  'php://stdout' when processing a web page b/c STDOUT is not available.
- Corrected TOutputWriter to write to the output rather than stdout.
- Added README.md text for starting the PHP Web Server Action after installing the application.

+## Built-in PHP Test Web Server
+
+The built-in PHP Test Web Server can be used to immediately start developing and testing a web application.
+The web server is started with command (assuming the above application in the directory "app")
+
+```sh
+cd app/protected
+./vendor/bin/prado-cli http
+```
+
+The application is then accessible on the machine's browser at `http://127.0.0.1:8080/`.  The built-in web server is enabled when the application is in "Debug" mode or is enabled in the application configuration parameters.
