Allow to reload changes on the `Conflict Solver` window

Most times the conflicts I solve are so hard to deal with, I have to open the text editor to properly deal with them (like rewrite code).

But when I go back to the Smartgit `Conflict Solver` window, the changes in the file system are not reloaded. 

It would be very welcome if Smartgit asked me whether I would like to reload the changes on the file system
