[Freeciv-Dev] (PR#13542) alt-left-click same as middle-click

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=13542 >

This patch changes alt-left-click to be the same as a middle-click.
This hopefully allows windows or mac mice without middle buttons to have
a middle-click behavior (which pops up the tile info).

Note that in X alt-left-click is usually taken by the window manager.  I
tested this however by killing the window manager and clicking real fast
before it was automatically restarted.  Presumably windows and mac
wouldn't have the window manager problem.  However there are other
choices like ctrl-shift or MOD2 (whatever that is).

Note that 1-button mice will still have a major problem.  And there's no
way to do the wake-up-sentries action (normally ctrl-MMB).

For 2.1 we should really find a way for all these mapview actions to be
configurable.  This patch is made for the dev branch but intended mostly
for 2.0.
