comments and colors are not compatible in commands

[mwestphal]

Describe the bug It is supposed to be possible to set colors using a dedicated formating using a command set color #000000

However # is the char for comments so the command above doesnt work and it is required to use: set color "#000000" or set color \#000000 to be able to set the color as expected.

To Reproduce Steps to reproduce the behavior:

1. Open f3d
2. Press Esc to open the console
3. set render.background.color #000000
4. Error

Expected behavior No Error and background change

Suggested Implementation

A way to control the tokenizer and being able to disable comments or control quotes behavior would work, as this could be used in interactive console only.
