The version check failed on subrelease versions (as the 1.2.5-1 rebuild done for Mac) and detected an updated version that is in fact an outdated one. Rework the comparison completely, move it to the Utils class and display some more information in the status bar upon update check. Especially keep a notice in the status bar if an updated version was found. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@26788 a1c6a512-1295-4272-9138-f99709370657
