Extensions on existing code:
* clock:     mono support
* usb:       add PC->calc reading, and interrupt pipes
* fs:        support RAM files
* fs:        support USB streams as generic file descriptors
* fugue:     support glob() to abstract away BFile entirely
* fugue/fs:  offer a primitive to remove recursively, which is native in Fugue
* bfile:     implement the optimization-restart as realized by Kbd2
* kernel:    better restore to userspace before panic (ensure BL=0 IMASK=0)
* project:   add license file
* kernel:    group linker script symbols in a single header file
* core:      try to leave add-in without reset in case of panic
* core:      use cmp/str for memchr()
* r61524:    brightness control and clean the file
* core:      review forgotten globals and MPU addresses not in <gint/mpu/*.h>
* core:      run destructors when a task-switch results in leaving the app

Future directions:
* Audio playback using TSWilliamson's libsnd method
* Serial communication
* Make fx9860g projects work out of the box on fxcg50
* Base for Yatis' threads library
