Suggestion: Add \ to escape markdown

[advaith1]

So \_ would output an actual underscore instead of italicizing text.

If user has many underscores or asterisks in their message, it means that they have to escape all of them which is bothersome, that's why I'll add an exception to Markdown that it won't style anything if the message starts with \ character. It's not used widely so it should not cause any issues.
