Added global printing API

Also added a configuration editor for editing the printing queues.
Added stub for OperationPrinterJob (WIP)
OperationPrinter working

Uses a customizable HTML-page to layout the contents. No special magic
here other than the backstage-usage of ObjectFormatter to parse the
HTML-file and replace the macros. This makes the page fully customizable
without deeper programming knowledge, except maybe basic HTML.

The route-plan-image is realized as a special HTML-feature called
"embedded img", which embeds the Base64-encoded binary image file
contents. This allows us to circumvent some shortcomings with the
WebBrowser-control, which does not reliably (at least not on my two
testing PCs) parse/include a <img src="" /> that links to a file in the
same directory as the HTML page. Using the embedded Base64-contents is
not really slower but works bulletproof - at least as far as I could
test.
In case of an error in retrieving the route image, or GoogleMaps not
finding a result, a placeholder image is displayed - neat.
Updated diagnostics feature of GDI printer
Updated PrintingQueuesTypeEditor

- Added missing CopyCount
- Moved converters to contracts assembly
Refactoring of staticmap-calls
Updated type editor to allow multiple selection of printing queues
Be more verbose if template file not found
Fixed unreliability with IE < 9

Using embedded images (for the route plan image) as Base64 is
sophisticated, yes, but the IE in versions earlier than 9 would (if at
all) only support 32 kB of such data! This renders it unusable, since
the .Net Framework uses the IE for its WebBrowser control.

Solution: Don't use Base64-embedded image. Instead, store the route
image as a temporary file and include the full file path to this file
inside the HTML. This works far better. Also, remove the file after it
has been used.
Added support for printing multiple pages

If the generated HTML results in an image too big for one page, the
content is split across multiple pages.
Updated GdiPrinter

- Require PrinterName if PrintServer is set
- If PrintServer and PrinterName are specified, use
"\\Server\Printer"-format for printing
