Add Help button in enblend options dialog

[zarl]

The dialog can be found in
editor window >> Stitcher tab > Processing: Blender: enblend: [Options]

It would be nice to have a help button just like the one available in the preferences dialog (grouped with the Cancel and OK buttons). In this case it should probably link to /help/Enblend.html of Hugin's built in help pages. That way users can quickly look up command line arguments available for the current version of enblend without cluttering up the UI with a list of available options. (note to self: panotools wiki pages need an update to reflect the new command line arguments of enblend and how to combine them, also with a comparison to the behaviour of earlier versions of enblend prior to version 4.2)

Thanks, Thomas!

I'm already looking forward to the next beta version.

Hello Thomas,

earlier versions of Hugin displayed the help files in the user's standard browser. Now an integrated help viewer is used.

The help button now opens such a window but that can't be scrolled etc. at least on OS X since the enblend dialog is a modal window. I'm not sure how this can be solved in an elegant way without making the user close the dialog again to read the help page.

Cheers,
Carl

As a follow up this problem also affects the help button in the Preferences window.
Tested on OS X 10.11

I only can think of a quick solution for the enblend options dialog: The button could also be placed directly in the main window which is not modal.
