Allows for speeding up end of day animation #323

[Pathoschild]

I made a few changes to fix the handler not applying.

The caveat is that we need a specialized event to run handlers on the shipping screen, and SMAPI will show a warning in the console:

Bypassed safety checks

These mods bypass SMAPI's normal safety checks, so they're more likely to cause errors or save
corruption. If your game has issues, try removing these first.

• Fast Animations

Before I merge this, I want to see if SMAPI can raise the normal events on the shipping screen (before the actual save process starts) in an upcoming version, so we can avoid the warning.
