[B] Fix chat formatting bug

The Issue:
For example, the /reload command, sends coloured message, however (as shown in the screenshot below) these colours are carried over to the ending "[" of the message. Making it unorganised

Justification for this PR:
The current message handling is unorganised. Example: http://puu.sh/4RmzV.png

PR Breakdown:
Self explanatory.

Testing Results and Materials:
I have not tested the code, but there is no reason for this to not work as it is straight forward.
