Save System Trace on exit and allow easy retrieval after restart.
The System Trace isn't preserved when quitting Rockbox Utility. Change this so the last trace is saved in the cache folder, and add a button to the trace window to allow easy saving it. Should help in cases where users have problems but restart Rockbox Utility before saving the trace. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25313 a1c6a512-1295-4272-9138-f99709370657
