Handle individual verses in references

[bryanforbes]

Currently, references like John 19:13, 17, 20 aren't recognized. The verse parser should be updated to handle this.

I took a look into this issue and ended up rewriting the entire verse parser in a less... RegEx heavy way. In doing so I took some liberty with how the whole thing works and the assumption I made is that it would be grabbing implicit verse references from the text. However, it is fairly simple in structure and really could be fairly easily adapted into the code of the bot.

I don't know if you ever saw this but I think that it is still a patch worth looking into just for the ease of quoting multiple sections from the same chapter.
