* Reorganize namespaces
- Most types are now moved into the `melonDS` namespace
- Only good chance to do this for a while, since a big refactor is next
* Fix the build
* Add Platform::Log and Platform::LogLevel
* Replace most printf calls with Platform::Log calls
* Move a brace down
* Move some log entries to one Log call
- Some implementations of Log may assume a full line
* Log the MAC address as LogLevel::Info
also including:
* getting rid of shitty strings
* all new, cleaner ROM handling code
* base for DSi savestates
* GBA slot addons (for now, memory cart)
