Up initial poll call to 10 seconds.

This has a couple of effects:

1. Compile failures do not happen so quickly that the supervisor gives
up and the app stops.
2. The first poll is delayed, so any changes will have a lag time.
3. Remix will continue trying to re-compile every 10 seconds
indefinitly.
