Updated - colour bugfix

This is a minor bugfix release to resolve a rare colour related issue in the previous VDP 2.7 and 2.8 releases. The issue only occurred in colour games which specified the colour code for "current", rather than specifying a specific colour.  For example, Beyond Zork was not affected. The only game known to me that was impacted was Ghosts of Blackwood Manor, although I'm sure there could have been others. 

Nonetheless, it's fixed now so please download and enjoy!
