Pretty formatting for post information

[n7st]

Currently, messages are dumped out in IRC channels like this:

pics Do you know what Yosemite means? https://i.redd.it/zqxsuvp9ajs61.jpg
pics It do be https://i.redd.it/zkwublx7ajs61.jpg

Instead, it should follow the original SubWatch format:

message = '%s "%s" posted in /r/%s by %s. %s%s' % (
    style.color(prefix, style.GREEN),
    thread.title,
    sub,
    thread.author,
    thread.short_link,
    style.color(' NSFW', style.RED) if thread.over_18 else ''
)
