Make move.js YUI-compressor compatible.

[rstacruz]

Right now, it's structured this way:

exports.Move = function Move() { ... }
Move.prototype.x = ...

This presents a problem as YUI compressor may mangle function Move() into a non-named function. We've encountered this problem using move.js with Jammit.

damn, uglifyjs does the same, that's really annoying. IMO it's really wrong to alter code just for a compressor, YUI must have a setting or something. I'd rather just do:

function Move(){}

exports.Move = Move;

assuming it does not mess with function statements haha

[rstacruz]

YUI only has the following options:

• munge (default false) -- will squelch variable names as it sees fit
• optimize (default true)
• preserve_semicolons (default false)
• charset (defaults to "utf-8")
• line_break

closing, if this is still an issue feel free to open :)
