Feature: Flags to add events to scripts

This would allow advanced users the freedom to create really complex and intricate custom flags, by allowing them to edit or create their own subactions from scratch, giving power similar to HSDRAW and surpassing the functionality of the Crazy Hand editor. Since custom flags are exportable, it also has a nice perk of allowing these more complex mods to be easily shared and updated after they're completed, and could eventually also be implemented as a main Flag of the randomizer.

This involves creating a syntax and handling cases for every event type. This could be done to be generic, for example

|eventadd_eventtype index [tags]|

Then you could use additional commands to modify it from there.

Or it could be event specific, and have everything be done in one command.

|hitboxadd_index damage angle growth etc...|

Commands for removing events would also be necessary. Modders would have to keep track of the indexes, which could be annoying, but in theory should allow for some really cool flags. Things like turning every taunt into a Shine, for example.
