Support parameters in wire[] to override dependencies

(One of the ideas from ScalaDays 2014 - by @matthewfarwell)

The wire[] method could accept parameters, which would be used to wire an instance of the given type; the parameters would take precedence over (override) vals/defs in wider scopes.

Example usage:

class Service(s2: Service2, s3: Service3, config: Map[String, String])

lazy val s2 = wire[Service2]
lazy val s3 = wire[Service3]
lazy val defaultConfig = Map("username" -> "default")

// here the given map would be used instead of the default
lazy val sA = wire[Service](Map("username" -> "admin"))

// here the default config map would be used and an alternative Service2 impl
lazy val sB = wire[Service](new Service2(...))

A parameter which doesn't match any of the constructor parameters of the wired type would result in a compile-time error.

This can be useful for:

• providing alternative implementations only for a single usage
• providing configuration values on a per-instance basis

Start by reviewing the wire[] API and the constructor-matching behavior described in the examples. Define how supplied parameters override wider-scope vals/defs, and verify that unmatched parameters produce a compile-time error while the shown Service examples resolve as intended.
