Merge of branch-1.3-Fl_Printer, with the following main changes:

 (1) adding Fl_Device class (and more) for device abstraction
 (2) adding Fl_Pinter class (and more) for printing support.

Todo: Code cleanup, update dependencies, remove/replace test print window.
I'm looking into converting the test window popup in a global shortcut
that would pop up the print dialog now...
