Subject: Issue #1603 - Part 2: Split some classes out of ScriptLoader.cpp

This splits ScriptLoader up the same way Mozilla did with the exception of
ScriptRequest due to the fact that ScriptLoader and ScriptRequest are
interdependent and would create a circular dependency if split apart when not
using unified building.
