History dialog UI tuning

[akks]

Another ticket from Russian forum.

Ilis noticed that links to user and changeset in History dialog right panel autiohides too often (see attachments). (from me - it is beacause of tricky cobination of FlowLayout and GridBagLayout). I can not make a patch myself, too complex Swing :-)

He also propose to add another hyperlink to left panel conext menus (we have "Open changeset #####" but not "Open user /name/(####)"), so user id can be excluded from table to save space.

In 5050/josm:

UrlLabel class simplification by Zverik, better label layout in VersionInfoPanel (see #7450, #7326)

[akks]

I have aligned user, changeset and their link into 2x2 grid. It should look better on lower horizontal resolution and widnow size.

Same happens with the lower buttons at the bottom of conflict manger member dialog !

The dialog 's position is not remembered. It is always opened in the centre of the screen.

and the "Cancel" button does not work.

see #7326 - History dialog: move user id to toolbar, remember size/position

For non-working cancel buttons, see #7813.

Does the issue with the conflict manger member dialog persist? If so, please open a separate ticket. Thank you!
