- 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.

…/Performance Mode

- Better documentation for TOutputWriter.
- TStdOutWriter removes flush and sets the _stdout var.
- TWebServerAction corrects Port var, setAll "null" check, and minor tweak to the CLI help text.

specify that it can be turned on only for the built in dev server with the getOnlyDevServer configuration option
