downgrade grunt-contrib-connect 0.10.1

[bjoernHeneka]

downgrade grunt-contrib-connect to version 0.10.1 because of changes … in connect 3.x.
this causes an error while upstart:

Warning: Object function createServer() {
function app(req, res, next){ app.handle(req, res, next); }
merge(app, proto);
merge(app, EventEmitter.prototype);
app.route = '/';
app.stack = [];
return app;
} has no method 'static' Use --force to continue.
Aborted due to warnings.
