site: rename to website.
First this is more consistent as we already have a website-build
directory. Then it is also useful for migrating to haunt as 'haunt
build' puts the generated website in a 'site/' directory, so without
this rename, when the migration would be complete we'd have site/site
instead of website/site.

Revision notes (9th March 2014):
--------------------------------
- recreated coreboot config from scratch
- GRUB loads even faster now (less than 2 seconds).
- Total boot time reduced by further \~5 seconds.
- Added crypto and cryptodisk modules to GRUB
- cbfstool now included in the binary archives
Development notes
-----------------
- Binary archive now have 2 images:
- With serial output enabled and memtest86+ included (debug level
8 in coreboot)
- With serial output disabled and memtest86+ excluded (faster boot
speeds) (debugging disabled)
- Reduced impact on battery life:
- 'processor.max\_cstate=2' instead of 'idle=halt' for booting
default kernel
- coreboot.rom (faster boot speeds, debugging disabled):
- Disabled coreboot serial output (Console-> in "make
menuconfig")
- Set coreboot debug level to 0 instead of 8 (Console-> in
"make menuconfig")
- Changed GRUB timeout to 1 second instead of 2 (in grub.cfg
- Removed background image in GRUB.
- Removed memtest86+ payload (since it relies on serial output)
- coreboot\_serial.rom (slower boot speeds, debugging enabled):
- Boot time still reduced, but only by \~2 seconds
- has the memtest86+ payload included in the ROM
- has serial port enabled. How this is achieved (from
X60\_source): Turn on debugging level to 8, and enable serial
output
- (in Console-> in coreboot "make menuconfig")
- (and build with grub\_serial.cfg and grub\_memdisk\_serial.cfg)
