Hand tool translations for zh-TW
Comments:
Line 56-58: "Gegen den Uhrzeigersinn" is shorter and more common than "Entgegen dem Uhrzeigersinn" (http://de.wikipedia.org/wiki/Drehrichtung)

Line 60-63: "Hand-Werkzeug" is also used in Acrobat

Line 124,133,..: "PDF" is not a noun. Acrobat, Wikipedia use "PDF-Datei" (="PDF file") instead of "PDF".
The English translation sounds just as bad: "An error occurred while loading the PDF.", "The PDF is not fully loaded for printing."

[CRX] Add a pageAction to omnibox showing PDF URL

In Chromium extensions, the viewer's URL looks like this:
chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/http://example.com/file.pdf

Furthermore, the PDF Viewer itself can also add something to the reference fragment:
chrome-extension://oemmndcbldboiebfnladdacbdfmadadm/http://example.com/file.pdf#page=2

Consequently, it is difficult to copy a clean URL (e.g. for sharing over mail)
without having to tidy-up the URL manually.

This commit solves this issue by adding a button to the omnibox,
which shows the clean PDF URL on click.
