Eloquent\Model: match @property annotation type

Eg.

class User extends Eloquent\Model 
{
    protected $casts = [
        "some_property" => "int"
    ];
}

Requires: @property int $some_property Should accept: @property int|null $some_property Should accept: @property int|anything $some_property

To consider:

[x] For id (or other $primaryKey) consider $keyType property (or "int");
[x] For _id suffix consider int (eg. user_id);
[x] For _at suffix consider Carbon\Carbon (eg. created_at);
- [x] Should consider any $dates properties as Carbon\Carbon too;
[x] For accessors consider the returned type;
- [x] From mutator, consider the accessor return type too;
[x] Should consider $casts value;
- [x] For int or integer consider int;
- [x] For real, float or double consider float;
- [x] For string consider string;
- [x] For bool or boolean consider bool;
- [x] For object consider object;
- [x] For array or json consider array;
- [x] For collection consider Collection;
- [x] For date, datetime or timestamp consider Carbon;
[x] For any other case consider mixed;
