Server started at 3450, not 3449 as in the readme

Just following along with the readme.

The figwheel server port in project.clj is 3450.

During "lein figwheel dev", I see:

Figwheel: Configuration Valid :)
Figwheel: Starting server at http://0.0.0.0:3450
etc.

And the wallet comes up nicely, just not on 3449 as in the readme
