Add a quick fix to import libraries with prefixes when the library name matches

[bwilkerson]

Given the following code:

var min = math.min(0, 1);

there should be a quick fix to define math by importing dart:math. This should minimally work for all of the dart: libraries, but it would also be good if it worked for packages that are already listed as dependencies. For example,

var current = path.current;

should have a quick fix to import package:path/path.dart.
