rhelmer@mozilla.com fdc0652561 - adds ability to set the browser height and width through the config.py file
- adds a few prefs to sample.yaml that disallows browser move, resize and the
running of java
- increase the default page load timeout in the framecycler to 25000 ms
- some changes made to the way data is passed between the framecycler and
talos, will make it easier to add csv data dumping support
