WIP : PAPPL Scan API Integration

[Kappuccino111]

Actively updating for solving #130, #131 , #133 , #134.

This isn't a complete implementation.

@michaelrsweet, the implementation is still a work in progress. All updates are regularly posted on the comments in #130

I have now pushed the scanner-accessors.c file. One doubt that I have is that papplSystemAddEvent() is pre-configured for printers, and hence passing a scanner object while using papplScannerResume() or papplScannerPause() creates warnings. Any ideas on how to proceed with this? For now, I am simply debugging to the terminal.

For now I would add a different version of papplSystemAddEvent that accepts the scanner pointer. Longer term we'll need to do something more coherent, of course, but for now a separate function will do just fine for a first implementation.
