Start DSiWare Support

- Added DSiWare detection
- Start INI Work for DSiWare. PUB and PRV save creation not added yet.
- Only modify VRAM if running on a flashcart (resolved Giana Sisters DS regression)
- Remove Card DMA configuration to align with nds-bootstrap removing it as a configurable value
- Show a message to the user if using akmenu-next for the first time
