PaperBot: When responding to multiple requests, align lookup results or post each response individually

[tahonermann]

When PaperBot receives multiple requests in a single chat, it responds with a single post with each response on its own line. This results in unaligned responses as shown below.

It would be nice if, when there are multiple responses, that each response (including the "Sorry, I could not find ..." responses) appear with the same alignment. This could be accomplished by inserting a blank line at the beginning of the post if there are multiple responses or by posting each response individually.
