Improve error messages information (#70)

[emilioastarita]

To address #70 handling composition of error messages with some helpers.

Example:

  class Ok {}

  @injectable()
  class C {
    constructor(public s: any) {}
  }

  @injectable()
  class B {
    constructor(public c: C) {}
  }

  @injectable()
  class A {
    constructor(public d: Ok, public b: B) {}
  }

container.resolve(A)

Will throw an exception like this:

Cannot inject the dependency "b" at position #1 of "A" constructor. Reason:
    Cannot inject the dependency "c" at position #0 of "B" constructor. Reason:
        Cannot inject the dependency "s" at position #0 of "C" constructor. Reason:
            TypeInfo not known for "Object"

nit: Any way we can format this to be a little more readable?

[emilioastarita]

[/ /,/ /].map(x=>x.source).join() as in b11ea0c

makes readability any better?

[Xapphire13]

Can we use the specific types rather than any?

[emilioastarita]

Yes, but I need to remove any from typeInfo map.

Something like this 144e07f it's ok?
