* 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
Turns out my system was affected by a bug with modifier remapping in
macOS causing some of my left/right modifiers to be swapped. This commit
fixes them to be the correct values.
Typically, modifiers are masked out of keypresses to distinguish
between hotkeys and keypresses. This patch prevents the numpad
modifier from getting masked out in KeyPress() and KeyRelease().
