Make sure document sending is disabled by default

[Tjzabel]

Through a quick conversation on #ritlug-teleirc, someone mentioned their API key was being sent through when sending over a document.

This feature was turned off by default, so I would like to double check to make sure this is actually working as intended. Document sending should only be done in channels where the owners feel it is okay for their key to be seen.

Steps to close this issue

1. Do a fresh clone of teleIRC
2. cp env.example .env
3. Update channel info in .env
4. Run teleIRC
5. Send over a document from Telegram
6. Make sure document does not make it over the bridge

The option is disabled in the example configuration file:

teleirc/env.example

Line 13 in 108b84d

IRC_SEND_DOCUMENT=false

I don't have a record of this conversation. Did we ask the person to check what version of TeleIRC they were running? Without more data or someone willing to confirm this, I suggest closing this as invalid. I think it is more likely they were running an outdated version of TeleIRC.

At this point, I am okay with closing this issue as invalid.
