Display the Subsurface manual in the help widget

Browse source 
This adds a helper function to determine the Subsurface data directory
(are we running from build directory? installed on Linux? installed on
Mac? - still need to add support for Windows). This same function is
then used by both the setup for Marble and for the help browser.

This assumes that the user-manual.html file has actually been built and
installed (which we don't do by default with the current Makefile).

Right now there are rendering issues with our manual in the help browser
widget - I'm sure this can be fixed...
