Client and server same path example

Show example for having a client and server route controller for the same path. I'm using this in production now to avoid using the `spiderable` package and it's working quite well.
fix RouteController render method to return result
update linkTo to accept dynamic params inline
fix bug with hasJustReloaded never getting set to false
bump version to 1.0.0-pre4
move helpers.js to client and server and fix urlFor, pathFor to...

... allow passing dynamic path values directly in the options like this:

{{urlFor route='someroute' _id=someid}}
oops, add the helpers.js file
Update README.md
Added note about 0.9 docs
Create Contributing.md
