displaymanager: Fix typos in displaymanager.conf.
displaymanager: Add my copyright to main.py.

I have already written a bunch of code in there.
displaymanager: Don't error if a DM is not installed.

If a display manager is in the list, but not installed, do not return an
error message, but only print a debugging message and proceed.

This allows distributions that support multiple display managers to list
them all, independently of what the concrete live image will be using.
displaymanager: Remove lightdm gdmflexiserver hack.

Remove the hack that symlinks /usr/lib/lightdm/lightdm/gdmflexiserver as
/usr/bin/gdmflexiserver.

Upstream LightDM removed their gdmflexiserver implementation in 1.9.4 in
2013:
http://bazaar.launchpad.net/~lightdm-team/lightdm/trunk/revision/1841

In addition, LightDM was already adding the path containing its
gdmflexiserver implementation to PATH, so there was no use symlinking it
into /usr/bin, potentially overwriting the original version from GDM.
This must have been a workaround for an ancient LightDM version that
didn't even do that.

And finally, the hardcoded /usr/lib/lightdm/lightdm/gdmflexiserver path
was wrong on Fedora to begin with (we had used
/usr/libexec/lightdm/gdmflexiserver, but now the file is completely gone
because upstream removed it).
displaymanager: Fix default session setup for GDM.

The default session setting in GDM is per user. Therefore, it is not of
much use to set it for the gdm user. (Nobody will log in as "gdm".)
Unfortunately, there seems to be no systemwide setting for the default
session, the AccountsService provides no such setting, and GDM just
hardcodes the fallback to use if it is not set in the AccountsService.
(GDM first tries "gnome", and if that is not available, it picks the
first session in the alphabet.)

Therefore, the best we can do right now is to set the default session
for the autoLoginUser. This is the case where it matters the most
anyway. We would also need the username of a non-autologin user in the
global storage to do any better.
displaymanager: Use libcalamares.utils.debug instead of print.

Use libcalamares.utils.debug instead of print to output a debugging
message during SDDM autologin setup.
displaymanager: Disable basic setup by default.

Add a "basicSetup" boolean setting and default to leaving this kind of
setup operations to the distribution packages (i.e., to
"basicSetup: false").
displaymanager: Fix the use of getent in the basic setup.

This also matches what the original shell script from Manjaro did.
displaymanager: Don't run xdg-icon-resource and update-desktop-database.

Don't run xdg-icon-resource and update-desktop-database in the basic
setup for KDM. These tools have absolutely nothing to do with KDM. KDM
does not ship any icons in the hicolor theme, nor a .desktop file (let
alone one that handles any MIME type, the only case in which
update-desktop-database is needed).

I know the original shell script from Manjaro called these when setting
up KDM, but this is really the wrong place. If you need to call these,
they need to go into another module, and you also have to call them
independently of the selected display manager.
displaymanager: Make the settings follow the naming convention.

Make the defaultDesktopEnvironment and desktopFile settings in
displaymanager.conf follow the naming convention used in the other .conf
files.
Update README.md
Automatic merge of Transifex translations
grub: Use bootloaderEntryName instead of shortProductName.

Use bootloaderEntryName instead of shortProductName as the
--bootloader-id.
grub/test.yaml: Simulate bootloaderEntryName instead of shortProductName.

That is what grub/main.py now expects in the global storage.
Fix unpackfs wrongly excluding separately-mounted partitions.

mount: Remember the extraMounts (and extraMountsEfi, if applicable) in
the global storage (as "extraMounts").

unpackfs: Read the extra mounts from the global storage to generate the
exclude list instead of trying to detect it from the "mount" command's
output, because the latter also includes normally-mounted destination
partitions.

This makes having separate partitions for non-/ mountpoints work again.
unpackfs: Fix error in list_excludes.

I accidentally removed the initialization of lst.
grub: Add an optional efiBootloaderId setting.

If the efiBootloaderId is set, it is used as the --bootloader-id when
installing grub-efi. The rationale is pretty much the same as for the
Gummiboot case.

If the setting is not used, the --bootloader-id is determined from the
branding's bootloaderEntryName (as before).
keyboard: Preselect the current keyboard layout variant.
displaymanager: Also look for display managers in /usr/sbin.
locale: timezonewidget: Use the system default font.

Don't hardcode the Cantarell font.
