[PULL REQUEST] GSoC Printing: part 4

Part 4 of the new GSoC printing module from Gehad.

Adds:
1) Better greyscale conversations when "print in color" is de-selected.
Due to a QPrinter->setColorMode() bug we are forced to rasterize the entire
page (profile, tables, everything) when in greyscale. We have faced some
limitations here including the fact that Profile2 support for custom color
tables is incomplete. Consider this the cheaper solution and if the GSoC
timeframe allows it, we can invest more time into attempting proper greyscale
vector prints using the custom color table and so on.

2) A preview graphic in the "Template edit" dialog
When editing a template, gitting "Apply will allow you to review your changes
in the dialog itself.

3) Custom CSS colors and color themes
Basically you can save your preferred color scheme, containing a set of
common colors and use it for all templates. Also, you can edit a template
itself directly and use a hardcoded color e.g. #fafafa for backgrounds.   

4) More generic fixes... 

ATM this is useable, but the stock templates aren't pretty yet; an important
thing on the TODO list is to get the already present templates to look similar
to what we in the previous print module (i.e. user-ready).

Feedback on the usability itself will soon be needed from the community!
ATM, given you have libgrantlee installed you can try building with
NO_PRINTING=0 and submit feedback to one of the related ML threads.
