Added QRCode to Install Page
Now generating direct install QRCode
New template with QRCodes

to directly install App + QRCode to the install page itself.
Template distinguishes between iPad/iPhone and desktop clients.
Install page reloads now to remove iFrame
Improved HTML template
Added QRCode info to presentation
Increased QRCode size
More logging in case of issues
Improved PPTX presentation
Refactoring: leaner API, parameter map used

Instead of extracting and passing each single parameter to all methods.
All request parameters usable in HTML template now
Removing outer HTML frame now configurable in tmpl
Page QRCode dependent of removeOuterFrame param

If removeOuterFrame is true the install page QR Code
points to the inner OTA-Service frame.
If removeOuterFrame is false the install page QR Code
points to the outer frame, the original Referer.
