Add subfolder url and other question.

[DeAlexPesh]

Hi.

1. How to mount a program in a subfolder? ex: http://domain.com/drawio/
2. DRAWIO_CONFIG no work, but in log all good. Menu Extras -> Configuration doesn't work either.

   ...
   window.DRAW_MATH_URL = 'math/es5';
   window.DRAWIO_CONFIG = {
   "language": "ru",
   "customFonts": [],
   "compressXml": true,
   "plugins": [
   "plugins/explore.js",
   "plugins/svgdata.js",
   "plugins/sql.js",
   "plugins/props.js",
   "plugins/trees/trees.js"
   ],
   "createTarget": false,
   "search": true,
   "showStartScreen": false,
   "autosave": true,
   "autosaveDelay": 5000,
   "ui": "atlas"
   };
   urlParams['sync'] = 'manual'; //Disable Real-Time
   ...

3. jgraph/export-server no work export. Log:

   warn: Handled exception: Could not find Chromium (rev. 1095492). This can occur if either
   1. you did not perform an installation before running the script (e.g. `npm install`) or
   2. your cache path is incorrectly configured (which is: /usr/local/drawio/.cache/puppeteer).
