Turns out modifiedgame was getting set during startup because of making it use G_SetGameModified. Uh, woops?

Remove irrelevant attempts at majormod setting for SOC events which explicitly can only happen if a gamedata is created.

* Refactor all instances of `majormods = true;` to route through G_SetGameModified, and catch a few spots I missed in the process.
* Make G_SetGameModified only console-print for major mods.
* Add amnesty to "major mod" detection while loading files with custom savedatas.
* Improved the console prints for command `isgamemodified`.

	* If your file defines state and object freeslots in SOC, you are allowed to modify those freeslots IN ANY SOC SCRIPT IN THE SAME FILE without being marked as a "major mod".
	* If your file contains broken unlockables/emblems that don't actually have effect for any reason, it's not counted as a "major mod".
* Added add-ons menu message for adding a "major mod".

First steps at implementing a mechanism that allows you to load non-cheaty good-faith mods such as custom characters with no Lua scripting, and play record attack with them. Features a few bad hacks and a few more areas of improvement; I'll try to iron them out before they hit `next` or `master`.

- Fix typo that could potentially invalidate the wait phase
- Prevent dying during target phase causing it to redirect to someone else

- SPB intensity now biases against high drift sparks + acceleration, instead of only acceleration.
- Slow speed is scaled w/ SPB intensity too

Partial revert of commit 92a60b32.

Fixed WANTED poster drawing over minimap, WANTED cursor being colormapped, and splitscreen position shifting stuff

Meant to do this in song-credits, since individual songs are now properly credited there.
