Make xp web [name] load the class xp.[name].Web

[thekid]

This PR makes it shorter to load specialized web applications by being able to refer to them with a lowercased version, e.g. xp web lambda Greet instead of xp web xp.lambda.Ws Greet. It saves only a couple of keystrikes but falls in line with 7f3f773, which aliased the command line option -m dev to -m develop.

Example

$ xp web lambda Greet
@xp.web.srv.Standalone(HTTP @ peer.ServerSocket(Resource id #124 -> tcp://127.0.0.1:8080))
Serving prod:xp.lambda.Web<Greet>[] > web.logging.ToConsole
