I've decoupled `Cookie` from the actual act of setting and getting
cookies. Currently there are a few limitations to how Cookie works that
this change mitigates:
0. `Cookie` currently changes the super global `$_COOKIE` when setting
to make the state of an application a bit more managable, but this is
bad because we shouldn't be modifying super globals
0. One can't actually change the `$cookie_class` once the
`Cookie::$inst` has been instantiated
0. One can't test cookies as there is no class that holds the state of
the cookies (it's just held in the super global which is reset as part
of `Director::test()`
0. One can't tell the origin of a cookie (eg: did the application set it
and it needs to be sent, or did we receive it from the browser?)
0. `time()` was used, so testing was made difficult
0. There was no way to get all the cookies at once (without accessing
the super global)
Todos are on the phpdoc and I'd like to write some tests for the backend
as well as update the docs (if there are any) around cookies.
DOCS Adding `Cookie` docs
Explains basic usage of `Cookie` as well as how the `Cookie_Backend`
controls the setting and getting of cookies and manages state of sent vs
received cookies
Fixing `Cookie` usage
`Cookie` is being used inconsistently with the API throughout framework.
Either by not using `force_expiry` to expire cookies or setting them to
null and then expiring them (which is redundant).
NEW `Director::test()` takes `Cookie_Backend` rather than `array` for `$cookies` param
BUG Resolve issue with DirectorTest breaking RequestProcessor
Injector::nest and Injector::unnest are introduced to better support sandboxing of testings.
Injector and Config ::nest and ::unnest support chaining
Test cases for both Injector::nest and Config::nest
Anchors should never make it to the server when they are in the browser URL bar, however tests are slightly different and some `Link()` functions may return a URL anchor. Instead of every test checking a link and stripping the anchor, I feel the Director::test() function should strip them off.
The functionality is easy to replicate in custom controllers,
and is too rarely used to be placed in core.
This also removes the `Member::is_repeat_member()` getter
and the `PastMember`/`IsRepeatMember` template globals.

Fixes an access issue where all public methods on FormField were allowed,
and not checked for $allowed_actions. Before this patch you could e.g.
call FormField->Value() on the first field by using action_Value.
Removes the following assertion because it only worked due to RequestHandlingTest_AllowedControllerExtension
*not* having $allowed_extensions declared: "Actions on magic methods are only accessible if explicitly allowed on the controller."
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
