filesafe/controllers/uploadController.js
Bobby Wibowo d9ddfe8e9a
Implemented stripping tags from images
... and optionally videos using ffmpeg (still experimental).

Users can choose whether to strip tags of their uploads or not from
the home uploader's Config tab (safe.fiery.me will have it disabled
by default).

The behavior will also be applied to the downloadable ShareX config.

Server owners can choose to force either behavior.

Make sure to add the new config from config.sample.js.

Fixed all instances of "e.i." to "e.g.".
My English sucks okay.

Bumped v1 version string.
