Added environment based application loading.

Server access to dev environments was previously blocked on every IP except 127.0.0.1
for the dev environment, and also only switched based on .htaccess file or direct url access.
This issue was fixed by detecting the APPLICATION_ENV, and changing which app.php
file was loaded. In addition, app_dev.php is explicitly blocked unless the dev
environment is set for the application.

Conflicts:
	web/app_dev.php
Added parameters.* to .gitignore

changes to parameters shouldn't be checked-in with projects, this is where
application-specific configuration is stored. Added the file to the gitignore to solve this
and should be updated as base configurations are added only.
Fix syntax error
Fixed a syntax error with conditional inside getenv parameter.
refactored demo code based on the latest changes from Symfony (mainly about CSS and images)

Use route names for login/check/logout paths in security.yml

It might be a good idea to switch the firewall login, logout and check paths to route names in `security.yml`, if only to draw attention to the fact that it’s possible (and probably a good idea?):

    secured_area:
        pattern:    ^/demo/secured/
        form_login:
            check_path: _security_check
            login_path: _demo_login
        logout:
            path:   _demo_logout
            target: _demo

As mentioned in symfony/symfony#1493, it’s apparently the right way to do it if you want a localised login page. At least that’s what I had to do after I prefixed the FOSUserBundle routes with `/{_locale}/`.

Changing composer name
Changed composer.json file to reflect the package as it's
own maintained fork of Symfony2, allowing it to be a separate
packagist package
