Remove "by admin" from blog byline and create comment bubble.

Trying to tinker with my blog byline.

First, I’d like to remove the “by admin” portion. Just gone.

Second, I’d like to change the part that currently says “No comments” so that it appears as a speech bubble, like this site uses:

If that’s not doable with my theme, is there some way to change the text? “No comments” just looks bad.

Third, and probably easiest, I’d like the date to match my title color.
