Changes in this release:

• This version is mainly an update to upstream 2.6.6. This include all changes from previous version, 2.6.2, up to 2.6.6, mainly new mappers and fixes for them and fixes in the core. See the upstream changes here.
• Some fixes from the QT/SDL version was ported into the Opendingux/RetroFW version. Mainly the new time stamp record for computing timing. This fixes an issue where frame timing starts to lose precision when application time gets to float large values by performing calcultions using integer math.
