Create a way to access all conf.yaml settings from anywhere without any defines

[ociule]

UPDATE: just use global $conf, this works from anywhere and does exactly that.

Right now, it one wants to change a setting between environments, he can add it to conf.yaml and then add a define in conf.php, like this:

conf.yaml:
==========
env:
    dev:
        default_admin_address: dev_admin@example.com


conf.php:
==========
define('DEFAULT_ADMIN_ADDRESS', $conf['default_admin_address'])

This is cumbersome and repetitive.

A service would be nice so that we could do:

$turb->env->default_admin_address

from anywhere, and without the stupid define.

Furthermore, this would finally allow using arrays (or any composite type for that matter) defined in conf.yaml. Right now, this is really ugly to do, as PHP does not allow array in constants (you cannot put an array into a constant).

(In [512]) Added a new Env service. Some doc. See #42

[ociule]

(In [513]) Register the new Env module. See #42

[ociule]

(In [514]) Use the new Env service from the ExceptionNotifier?. No more ugly static atributes. See #42

[ociule]

(In [516]) Phasing out the Env service - just use global $conf. See #42

Don't listen to me, I'm stupid, just use global $conf.

(In [517]) Removed the Env service - just use global $conf. See #42
