Prototype reload + other enhancements

[metalgearsloth]

See the release notes. Main one is prototype modifications are also reflected, not just comp changes, as I wanted to prototype different sprites in game and there was no easy way to do it.

Something I'm not sure on is this will also affect loadprototype / VVd stuff. Should we just have an overload that avoids updating modified components (e.g. setting it to true on live and making it so admins have to opt out?)
