Moonchild c04b682a88 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.
