Fix 'Recent Changes' dialog placement

On multi-monitor setups this was messed up, especially if one monitor
is below the other. Now get dimensions of 1st monitor and place based
on those. Preserve existing (strange?) placement logic.
Use SetDefaultSize rather than SetSizeRequest to allow resizing.
update News.txt with 1.2.0 release date
update README with a more explicit note about the Git dependency.
