The 'common.sb' sandbox file activates many features we do not need in the WebContent process. We should pare down the allowed items. This patch is the first step, which replaces the '(import "common.sb")' with a copy/paste of the contents of the sandbox profile. I also removed anything that was explicitly blocked in a later line of the sandbox, but wanted to minimize changes as much as possible in this first step.
