Restructure the way the new help documentation gets displayed

1) Make the _onSphinxDocumentation a single line instatiation of
documentation_window passing only the location within the documentation
tree instead of the whol documentation path.

2) Put all the logic in documentation_window to check for 2.9 or higher

3) If lower than 2.9 go to same documentation but open with broswer (no
longer requires a connection)

4) Fix logging string so if the path is not found it fails but sends a
logging string to the log
