First pass at a consistent default for load/saving files that don't have a

pre-defined location (ROM files and disassemblies, etc).
- Repurposed the snapshot load/save folders by changing OSystem::defaultSnapLoadDir to OSystem::defaultLoadDir, and similar for the save dir
- In Windows, this directory will now be 'Documents\Stella', while in Linux/OSX it will be $HOME
- Testing still required for Windows and OSX; only Linux is confirmed to work for now
