Configuration: Registers and xcsoardata directories

[coolwind@…]

Actually Xcsoar saves some parameters in windows registry database, and at the
same time loads a configuration from an Xcsoardata directory which can be
located in My Documents, on the Sd card, and other places. This is messy, you
never know what has been loaded from where. I think that registry should be
avoided, and the position of the directory xcsoardata should be hardcoded once
forever in the SD card. It's much better to know that your parameters were not
loaded because the directory was not correct, than to loose hours trying to
understand this cumbersome mechanism of registry fallback, imho.

It appears the profile file is first loaded into the registry to afterward load the registry settings into the memory. I really don't see any reason for this...
