#1231 Handle multiple selection in Project Files list context menu

[xsxs]

The problem:
After I translated a a project of 100 html files I'd like to open groups of ~20 files of the target files in my browser to re-read or proofread all of them group wise.

I can select a bunch files in the OmegaT's project window, but if I click on the right mouse button and choose open target file only one file is 'send' to and opened by the browser. :(
I'd expect that all selected files were opened in the browser hopefully in the same order a I see them in the project window.

Well a work around is selecting the files in their folder by Windows and click on open.
But is is only a work around because the number is limited (only 10 I guess)
that way and the html files in the folder aren't opened in the same
order of the project window. So if I realize an error I need to correct,
I had to start searching in the project window where is that file that I
want to change.

All that would be a lot 'smoother' if I would be able to open a bunch of
the target files in the browser (my case) in the same order of the
project window, which I now can proofread one by one and in case of an
error I easily do find the source file for a correction.
