Would you mind building olad/www/mobile.js please @nomis52 , as it looks like you did it last:
https://github.com/OpenLightingProject/ola/commits/master/olad/www/mobile.js

When I tried, I got a massive changeset compared to the relative change I'd made, or even if not changing anything, and I'd rather avoid creating new bugs if we can help it. Hence I'm hoping your build of the unmodified code produces the same output it did when you last ran it, then it will only have my changes on top.

If I rebuild with my old version of closure I get no diffs.

This is what I use to build:

trunk/closure/bin/build/closurebuilder.py --root=trunk/ --root=ola --namespace="ola.Setup" --output_mode=compiled --compiler_jar=compiler.jar --compiler_flags="--compilation_level=ADVANCED_OPTIMIZATIONS" > ../olad/www/ola.js

trunk/closure/bin/build/closurebuilder.py --root=trunk/ --root=ola --namespace="ola.mobile" --output_mode=compiled --compiler_jar=compiler.jar --compiler_flags="--compilation_level=ADVANCED_OPTIMIZATIONS" > ../olad/www/mobile.js

Sorry, this is too high risk to put into 0.10.1, please target master.
