Update Patcher

[rauenzi]

• Add documentation to patcher.
• Change how patches are organized to help avoid collisions. Before, if a single called callerA patched render of multiple react components inside discord (which often are just named t) both patchIds would have been identical causing children to go in the wrong location and not actually patch the right component.
• Allow return of callback for instead and after patches to be the retVal if the callbacks provide it.
• Add 3rd argument to instead patches which is the original function bound to this which is useful for some patches.
• Fix leak where children weren't reset on unpatch (super + slaves became children but unpatch still reset super and slaves as opposed to children

[rauenzi]

• Now also normalizes all class names in the DOM at load time since some elements will already be there with their non-normalizes class names
