Added markdown funcionality
Added markdown funcionality

Greetings to all contributors of this fantastic
project. In this commit, I have added markdown
funcionality to this mesenger. It works by
including a quite nifty little markdown
parser called markdown-js, and making necessary
adjustments for our messenger's purposes. It works
only outside of Zoeira Mode, because it cleans up
any html tags input by the user. Just keep that in
mind.
