staticDirs nested

[frissdiegurke]

I'm currently getting rid of the deprecated (only for plugins o_O) attribute staticDir and have the following suggestions for staticDirs:

• update wiki Writing Plugins for NodeBB
• allow nested objects as sub-dirs
• allow / for sub-dirs

Therefor I may use the following syntax:

"staticDirs": {
  "emoji-extended/maybeSomeSubDir": {
    "images": "node_modules/emoji-images/pngs",
    "css": "styles",
    "js": "scripts",
    "js/libs": "libs"
  }
}

Would be way more comfortable for some use-cases... At least one of nested objects and /-syntax should get implemented

I'd like to enable the use of / in staticDirs, but it's hard to detect the route. It may be possible...
