[Freeciv-Dev] (PR#12985) don't reread rulesets for no reason

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=12985 >

In this patch if /rulesetdir is run and the ruleset isn't changed, it
isn't reread.

A similar change would be desirable for savegame loading.  However this
doesn't seem possible without additional fixes since the ruleset data
has already been freed right before the load.  Basically this means any
load always has to load the ruleset data twice for now.
