Libreboot release 6 beta 5.

- build: added 'luks', 'lvm', 'cmosdump' and 'cmostest' to the list of
  modules for grub.elf
- Documentation: added pics showing T60 unbricking (still need to
  write a tutorial)
- build: include cmos.layout
  (coreboot/src/mainboard/manufacturer/model/cmos.layout) files in
  libreboot_bin
- Documentation: added ../docs/howtos/x60tablet_unbrick.html
- Documentation: added ../docs/howtos/t60_unbrick.html
- Documentation: added ../docs/howtos/t60_lcd_15.html
- Documentation: added ../docs/howtos/t60_security.html
- Documentation: added ../docs/howtos/t60_heatsink.html
- Documentation: Renamed RELEASE.html to release.html
- Documentation: removed pcmcia reference in x60_security.html (it's
  cardbus)
- Documentation: added preliminary information about randomized seal
  (for physical intrusion detection) in x60_security.html and
  t60_security.html
- Documentation: added preliminary information about
  preventing/mitigating cold-boot attack in x60_security.html and
  t60_security.html
- Documentation: added info to ../docs/index.html#macbook21 warning
  about issues with macbook21
- Documentation: X60/T60: added information about checking custom
  ROM's using dd to see whether or not the top 64K region is
  duplicated below top or not. Advise caution about this in the
  tutorial that deals with flashing on top of Lenovo BIOS, citing the
  correct dd commands necessary if it is confirmed that the ROM has
  not been applied with dd yet. (in the case that the user compiled
  their own ROM's from libreboot, without using the build scripts, or
  if they forgot to use dd, etc).
- Split resources/libreboot/patch/gitdiff into separate patch files
  (getcb script updated to accomodate this change).
- Re-added .git files to bucts
- Fixed the oversight where macbook21_firstflash wasn't included in
  binary archives
