Kernel: Implement TerminalDriver for Framebuffer device
...
Use this new FramebufferTerminalDriver for terminal instead of the
old VesaTerminalDriver. Only drawback with this is that framebuffer
device can only be intialized after DevFS is initialized.

Bootloader: Add cache to ext2 inode data block indices

This reduces the number of read calls with current kernel size from
~1700 to ~700 (60% performance boots). Loading the kernel is now alot
faster.
