Hopefully fix ext not working (assuming subfolder setup) + some cleanup

[dsevillamartin]

Fixes hopefully #17

Changes proposed in this pull request:

• I'm assuming the ext did not work with subfolders due to the register path check
  • Please check whether it did/didn't work, and whether this PR fixes it if necessary
• JS cleanup
  • Use Flarum prettier
  • Add Flarum tsconfig
  • Update to Webpack 5

Reviewers should focus on:

• Mainly the register path thing on subfolder setups

Confirmed

• Frontend changes: tested on a local Flarum installation.
• Backend changes: tests are green (run composer test).

Is there a way I can test this merge request on my forum before it is merged?

[dsevillamartin]

@ekumanov Yep! You can run composer require fof/stopforumspam:dev-ds/fixes-cleanup.

@datitisev thanks, just tested it and can confirm it finally works now, thank you! When you release it, how should I switch to the released version (from the dev branch, although they will be the same as content)?

@ekumanov Looks like composer require fof/stopforumspam will upgrade from dev to stable. So you can run that when it's released - I'll ping you and let you know 🙂.
