Adding express typings

This is not the most up to date typings but that's ok. We don't need
that many express features in our application so as long as a basic
application compiles, we're good to go.
Adding express

The TypeScript definition does not match the version but at least it
is close enough.
Removing the variable type decorator

This causes type stuttering and is really irritating. TypeScript
should be able to figure this out for me.
Adding the node dependency

Apparently dependencies are not recursively installed from tsd.
Improving the typescript compilation task

It now warns on an implicit any in the code and will also work with
external modules.
Bringing the code style more in line with Palantir

Palantir has reasonable defaults. The explicit typing became really
irritating and was not necessary for type safety.
Setting up the basic express app

Now we can at least handle the express service simple with the
TypeScript and run the code with npm start. This still does not solve
how it will work on heroku though.
Adding hot code reloading

The express server will now hot code reload all of the changes using
grunt. This basically involves a watch tasks on the TypeScript files to
recompile and then a watch task on the JavaScript files to reload the
server.
