diff-ext 1.8.5 released

diff-ext 1.8.5 adds Ukrainian translation and context menu icons.
I would like to thank Dmitry Gordiyevsky and Andy Kovtun for help with Ukrainian translation.

There was a regression in diff-ext 1.8.4.
This build fixes the regression.
If you have diff-ext 1.8.4 please update to diff-ext 1.8.5
