create ch2 mod for easier version updates

[erosson]

hey, when did they document mod creation? https://www.clickerheroes2.com/creating_mods.php

via https://www.reddit.com/r/ClickerHeroes/comments/98aspk/not_so_random_mod/

I'm imagining a mod that writes the planner's files to disk somewhere (with no in-game effect), completely replacing yarn export:chars. this would be much easier than the stupid copy-paste dance I have to do on every version change, and I could do some simple updates entirely in windows without rebooting or starting a vm.

could also be a standalone swf that writes to disk, instead of a mod. the key is that, in windows, it writes to disk instead of requiring copy-pasting - keep the effort required for version updates to a minimum. this is possible in windows because AIR runs there, and AIR can write to disk. there is no updated AIR environment in linux, so SWFs can't write to disk. (I tried very hard.)

this is also important so other people can update the planner if I ever stop playing or get hit by a bus. Right now, requiring linux for any update is going to stop many potential contributors since it's a windows game, and it slows me down too because I don't wanna reboot.

got the basics of this working. it still needs some polish:

• [x] write latest.json to the ch2plan checkout dir, instead of the desktop. probably need a text file next to the swf or something, to tell it where that is.
  • C:\Program Files (x86)\Steam\steamapps\common\Clicker Heroes 2\mods\active\ch2plan-exporter.json: {"ch2plan-path": "C:\\Users\\eross\\code\\ch2plan"}. must add this manually; if missing, it'll write to the desktop.
• [x] how best to run the postprocessing afterward? is this simple enough to rewrite in as3 so the only recurring directions are "open ch2, git commit, git push", or do we add the extra postprocessing command between "open ch2" and "git commit"? either way, can we do it from windows?
• [x] how best to handle the diffs of specific important as3 files in ./ch2data? the mod can't export ch2 source code or run a decompiler; probably needs an extra recurring step. again, from windows would be ideal, since we run the game there.
• [x] document how to use/change this in CONTRIBUTING.md

yarn dev, yarn build, yarn start, yarn export:as3, and yarn export:postchars now run in windows - that should be enough to do a complete version update from windows.

Flash doesn't seem to want to load other swfs in the browser anymore, so the exporter mod is now the only way to export data from ch2. It's easier to use anyway, so that's fine.
