Filter by date when opening files

Hi Alan — great suggestion, thanks for taking the time to write it up.

This is done and lands in the next update (v2.4.1): in the Open/Save file browser you can now click the Modified column header to sort by newest, and click again to flip to oldest. The same works for Name, Size, and Kind, folders always stay grouped at the top, and it remembers your choice next time.

While we were in there we also added a date filter next to the search box — jump straight to files from Today, the last 7 or 30 days, this year, or a custom range on a calendar — so tracking down "the drawing I worked on last week" in a big folder is quick.

Thanks again for the idea; it made the whole file browser better.
