Launches the Sunrise browser on webkit nightlies

When launched (for instance) on Webkit r34130 this Automator shell script boosts the Sunspider javascript results from:
4106.8ms +/- 0.4% to 2696.4ms +/- 0.4%, and
Acid3 test from:
74/100 (linktest failed) to 100/100 (linktest failed)
Stability seems unimpaired.
Use in Dock to launch Sunrise.
