- Note (Kevin Kofler): Grub will fall back to a LILO-style installation,
  using blocklists to reference the blocks inside a larger partition,
  with the same caveats LILO had (need to reinstall whenever you do
  anything to the partition that will move those blocks around).
- Setting flags (EF00, EF02) or creating grub boot partition should be
  handled within 'partition' module.

- move fail-check out of loop
- add more debug lines

- add more debug informations
- simplify gpt detection code

- add 'bios_grub' flag when gpt table got detected
- grub: add --recheck at installation

- remove unneeded double code
- add kernel lines to config

- use --target=i386-pc flag for grub installs
- use str.format()

Copy the setting into the global storage. Make the EraseDiskPage in the
partition module and the grub and bootloader modules read it from there.
Do not hardcode /boot as the path anymore.

I set the default path to /boot/efi because I think that's the most
common setting. At least Fedora and Debian use that path. But we can
change the default setting if you think I'm wrong, as long as it remains
configurable.

There is no separate setting for efi_directory_firmware anymore. The EFI
firmwares expect that directory to always be in the "EFI" path in the
EFI System Partition. Distributions using /boot/efi actually have that
directory under /boot/efi/EFI.

Allow setting bootloaderEntryName in bootloader.conf. If not specified
there, the setting will be taken from branding.desc.

Use it in the bootloader and grubcfg modules instead of
shortProductName.

This avoids the duplication between the bootloader and grub modules.

This is particularly useful if the full product name contains
"GNU/Linux" or "Linux", because e.g. "Generic GNU/Linux GNU/Linux" does
not make sense.

Change any '/' slashes to '-' dashes. Also change spaces to underscores
while we are at it.

Remove the redundant "distribution" setting from bootloader.conf.

locale hardcoded to en_US until local globalstorage is available
run pep8 on bootloader main.py, plain switch from subprocess to chroot_call fails for gummiboot call

Some distributions (e.g. Fedora) use grub2-* (resp. /boot/grub2/) names.

Fixes #123.

add hibernate option to .conf
create a fallback entry in gummiboot menu
re-add firmware to globalstorage, simplifies this module, will be needed to add more OS to gummi
