Bringing Generator Express Up to Date

Various commits related to bringing generator-express up to date with where grunt/yo are right now.

 - Removes regarde and grunt-contrib-reload
 - Replaces the aforementioned with grunt-contrib-watch
 - Sets the package name based on the cwd of the project instead of hard coding "application-name"
 - Several dependency updates to make everything play nicely

I also have a [PR out on grunt-develop](https://github.com/edwardhotchkiss/grunt-develop/pull/9) so that we can more accurately bind to the restarting of the node server instead of guessing based on timing.  If/Once that gets pulled in, I'll update.

If you want to give me commit access like you mentioned before, I'm totally on board with that.  Let's make this the go-to express generator :-).
