blessed by the strongest, this will surely be the final version
* latest important update: **this one**
* latest gzip edition of the sfx: [v0.11.18](https://github.com/9001/copyparty/releases/tag/v0.11.18)
* if upgrading from v0.11.x or before, see [v0.12.4](https://github.com/9001/copyparty/releases/tag/v0.12.4)
new features
* click an open tab to close it (thx daniiooo)
bugfixes
* multipart POSTs could get incorrectly rejected with `protocol error after field value`
* had a `0.14%` chance of happening (worst-case; 1400 mtu, 2 offsets)
* affected stuff like saving markdown documents, renaming files, ...
* did **not** affect file uploads, and reverseproxy probably helped prevent it
* filedrop UI could let you try to upload/search without the necessary permissions
* purely cosmetic, would immediately fail with a slightly cryptic error message
* apply a different equalizer tuning for some browsers
* some permutations of chrome and win10, and also some phones, have incorrect Q scaling at higher frequencies, causing treble to be massively boosted
* now tries to detect this by sampling the frequency response at 15khz and setting different gains (less dangerous than touching Q)
other changes
* search ui does not initiate searches as eagerly if the textbox has a very short value
* helps prevent overloading slow browsers with accidental wildcard searches
