To make a GRUB bootloader installation (on the HDD) work, the graphical
console has to be disabled in /etc/default/grub :

	GRUB_TERMINAL=console

Remember to apply the change using update-grub. The menu is displayed in
text mode.

This is also discussed in #4

Closes #24

This should de-duplicate and simplify our docs.

Fixes #27

Now our scripts start with _where_ it should be run. x230_*.sh should
be run on the x230 where Skulls should be installed. external_*.sh
obviously not.

This also adds the -f <flasher> option and an interactive menu if not
specified.

Also, this updates our script commands in the documentation and moves the
"flashrom chip config" section under the "background" section.

Closes #26

we stick with set -e so we need to catch errors manually if need be

This adds an experimental option to choose a chip from flashrom's list
using our own heuristics. If successful this should become the default
behaviour when when "-c" is not specified.

Basically this should completely replace the documentation section
"flashrom chip config" at some point.

Adresses issue #26
