Board should allow more file types

[microwavesafe]

At the moment the board is very restrictive on uploaded file extensions. For instance I couldn't get it to upload a gcode file no matter what file extensions I tried. I realise there are probably security concerns, but if we allowed say .txt it would help and I can't see how it would be abused. It means I can attach gcode rather than putting it all in line making the message thread a bit long!

agreed! I tried to post the gcode from my single line drawing and after some seriously frustrating 15 minutes, decided to just up it to the wiki.

I'll add the .txt extension along with .pdf sometime later today.

OK, I enabled the plain text extension group: (.h, txt, nc, ngc, and many others) are now on the 'allowed list'.

Added PDF and other 'document' extensions to the 'approved' attachments list.
