BindingType issues

[Nyholm]

The BindingType class changed it constructor in puli/discovery#33. We have about 500 places in our code where we use that constructor. The all have to be changed.

The new BindingType requires you to have a $bindingClass is that really necessary at construct time? Most of the calls to that constructor does not have that info.

The BindingType constructor changed in this way in order to enforce a type to be used with one single binding class. That is, if you declare a binding type My\\Interface for classes, then only classes should be bound to this type, not resources.

There is a pending PR to adapt the Manager component here: puli/manager#56

The final goal is to declare binding types and bindings like this:

{
    "provide": {
        "Some\\Plugin": "My\\PluginInterface",
        "Some\\Other\\Plugin": {
            "binding-type": "My\\PluginInterface",
            "parameters": { "alias": "phpdoc" }
        }
    },
    "binding-types": {
        "My\\PluginInterface": {
            "accept": "class",
            "parameters": {}
        },
        "my/translations": "resource"
    }
}

Would you like to work on this?
