ChromeOS should record FileBrowser.CreateNewFolder.... events

Added UMA user action implemented in http://codereview.chromium.org/8490014/
to extract_actions.py, updated chromeactions.txt.

Note: when I ran extract_actions.py --hash I saw a number of new actions show up
in chromeactions.txt. Someone has probably forgot to update it.
I am only adding the one line related to my action in this patch.
