Added ServerShell for PHP Built-in Server

[shin1x1]

Hi, I would propose adding new Shell Command.It is ServerShell.

ServerShell provides a httpd server for CakePHP application without other httpd server(Apache, nginx etc).

It is use PHP CLI build-in server.

Use case is below.

1. default (http://localhost/)

$ cd /path/to/app
$ ./Console/cake server

Welcome to CakePHP v2.2.0 Console
---------------------------------------------------------------
App : app
Path: /path/to/app/
---------------------------------------------------------------
ServerHost  : localhost
ListenPort  : 80
DocumentRoot: /path/to/app/webroot
---------------------------------------------------------------
[WARNING] Don't use this at the production enviroment
built-in server is running...

2. specify ListenPort (http://localhost:8000/)

$ ./Console/cake server -p 8000

Welcome to CakePHP v2.2.0 Console
---------------------------------------------------------------
App : app
Path: /path/to/app/
---------------------------------------------------------------
ServerHost  : localhost
ListenPort  : 8000
DocumentRoot: /path/to/app/webroot
---------------------------------------------------------------
[WARNING] Don't use this at the production enviroment
built-in server is running...

3. usage

$ ./Console/cake -h

Welcome to CakePHP v2.2.0 Console
---------------------------------------------------------------
App : app
Path: /Users/shin/sandbox/cakephp_shin1x1/app/
---------------------------------------------------------------
PHP Built-in Server for CakePHP

Usage:
cake server [-h] [-v] [-q] [-H] [-p] [-d]

Options:

--help, -h           Display this help.
--verbose, -v        Enable verbose output.
--quiet, -q          Enable quiet output.
--host, -H           ServerHost
--port, -p           ListenPort
--document_root, -d  DocumentRoot 

4. PHP 5.3 or lower

$ ./Console/cake server

Welcome to CakePHP v2.2.0 Console
---------------------------------------------------------------
App : app
Path: /path/to/app/
---------------------------------------------------------------
ServerHost  : localhost
ListenPort  : 80
DocumentRoot: /path/to/app/webroot
---------------------------------------------------------------
This command is available on PHP5.4 or above

+1 but give it a better name like PhpWebserverShell and change the pull request to merge it into 2.3, not master.

Can we have shorter output, say:

    Welcome to CakePHP v2.2.0 Console
    ---------------------------------------------------------------
    App : app
    Path: /path/to/app/
    DocumentRoot: /path/to/app/webroot
    ---------------------------------------------------------------
    built-in server is running in http://somelocalsite.dev:80/

Also, [WARNING] Don't use this at the production enviroment is just noise imo, and should be documented in docs, not on each run.

This is not our indentation style for comments.

Also please use hard tabs rather then spaces.

[shama]

Indentation is off here, Cake uses hard tabs.

This change is also similar to #634

[shin1x1]

Thanks for all the comments!
I will fix comment, indentation, tab, and typo:D

@burzum Hi, I change the pull request to 2.3 branch.
thank you new name! PhpWebserverShell is a good name.

but I will enter many characters.

$ ./Console/cake php_web_server

ServerShell is shorter.

$ ./Console/cake server

@rchavik good idea! I try to shorter output message.

[burzum]

@shin1x1 I clearly prefer to type a few characters more in favor for a better variable, class or shell name than ending up with non specific and generic names. To be honest, at least for me, and I do not think for any person who's programming for some time it really doesn't matter if you type 6 or 12 chars.

[markstory]

I'd rather have the shorter name personally. php_web_server is a bit redundant, what other kind of server would you be starting other than a php + web server?

[rchavik]

how about http_server ?

also, is it possible to squash these commits in a logical chunks?

[rchavik]

nevermind about the squash, i just saw your #714. nice.

[shin1x1]

@burzum I think that variable, class name should be a specific, too. I type a few chars with code completion(Vim, Emacs, Eclipse). But shell name is need to enter full chars. so, I like short name.
