Update l10n for de: hand_tool_*, password_*, fixes

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."

Questions:
133: "request_password" is not present in en-US. Is it necessary in DE?

Why the difference in Line 103:
en-US: error_version_info=PDF.js v{{version}} (build: {{build}})
de-DE: error_build=PDF.JS Build: {{build}}
