Just in time for the holidays!  - Initial support for grammar checking. This version highlights common passive voice phrases.  - Wrapping improvements for plain text content, for example in a file containing markup.

Commentator can now operate on arbitrary lines of text, not just comments. For example, if you’re using Xcode to edit a markdown file and want to keep the spell check the text, or have bulleted lists nicely indented, you can do that. Note, when wrapping multi-line selections, if _any_ line in the selection is a comment, then only the comments will be wrapped. If no line in the selection has comments, then Commentator will wrap the non-comment lines. The wrapping length handling changed slightly. Previously comments would be wrapped at the first word break _after_ the comment length. Now it will break lines at the closest word break _before_ the comment length value. This makes it more predictable to guarantee lines don’t exceed the preferred length. Minor bug fixes for some cases that didn’t wrap correctly.
