Even more text-parser updates

• Fixed many small bugs.
• Pages can no longer be too wide to fit on screen.
• Very long words can no longer overflow the right edge.
• Adjusted styling on blockquotes to italicize those that are relatively short. This helps distinguish multiple short blockquotes from the surrounding text.
• Adjusted styling on list elements to avoid indenting entire articles when the article’s container is itself a list element.
• Added support for IDN hostnames.
• Improved filter accuracy in a lot of small ways.
• Made the filter less aggressive to significantly reduce the chances of ever stripping legitimate body text. I’d rather do it this way, even though it lets in more extraneous content.

I actually reached the bottom of the pile of text-parser reports for the first time. Thanks for the continued reports. You guys are awesome.
