strip_tags nuking <a> hrefs.

Since we turn HTML -> text via strip tags, we end up with borked links, IE:

```
<a href="http://example.com/">my example</a>
```

...turns into...

```
my example
```

...but should probably be...

```
my example (http://example.com/)
```

Also, this same sort of bug might exist for line breaks and such.
