Implement Printer Preference Persistence (Step 1/3)

Introduce new "Preferences" for printer overlays were added in PrefNames:  
- printing.page.header.left  
- printing.page.header.center 
- printing.page.header.right 
- printing.page.footer.left 
- printing.page.footer.center 
- printing.page.footer.right

The prefs file will look like this:

"printing": {
   "page": {
      "header": {
         "left": " ",
         "center": " ",
         "right": " "
      },
      "footer": {
         "left": "{date}",
         "center": " ",
         "right": " "
      }
   }
}

The steps for Printer Preferences:

Step 1:
 Introduce some sort of persistence for header/footer which is located 
in the Preference file.

Step 2:
 Allow PrinterQuery to read those stored preferences and setup 
PrinterSettings so that it will apply it when printing.

Step 3:
 Create a UI for the print preference, so that the users will easily 
change those printing settings.

NOTE: I tested the following approach while doing a simple Hack with 
PrintJob (if you see the previous patch), and it works great, with some 
bad after effect.
It was done for testing purposes. So I hope we are going in the right
direction.
