add un-escape code block to feedergrabber27

Add un-escape code block to `feedergrabber27`, lines 92-94.

In addition, since `title` is never actually needed, replace it with `_` in line 87, and then manipulate only `i.title`, never `title`, since in fact only `i.title` is being passed to the calling function.

If the `try` in line 87 fails, then we can continue the `for` loop; this is done in line 91.
