Basic Intel Exceptions
...
Any interrupt thrown for any Intel defined Exception is not only being caught but
displays an appropriate message to the screen.
Changes made in src/kernel/idt/idt.cpp

Interactive supervisor mode
...
To ease the pain of debuggin I can now interact with the system through a
very simplistic terminal. Hopefully things can be tested more easily by activating
the piece through a simple command. The max characters for a command is 10.
To achieve this I have had to make the following changes.
- Changed IRQ to update a global status variable
- Added a standalone keyboard driver with getKey functions
- Changed the main kernel loop to display a prompt
- Added a strncmp function to the clib/string file
