Remove AdjustForChangedSystemCapabilities() from StepMania.cpp

Remove this method, which only executes on Windows, which overwrites a few of your preferences based on whether or not you have at least 192MB of free RAM. The entire body of the function is wrapped in _WIN32 ifdefs. It is the only function making use of the LastSeenMemory value stored in Preferences.ini.
