Share some ./home dirs between version

[Ralf Mardorf]

Leave Pictures/ and Co. alone.

At least name the link Pics/, Picture/, pictures/, Pictures_2/, my_pics/
or similar and link e.g. my_pics/ against /mnt/home/foo/Pictures/.

IIUC the path in the meantime became /boot/Pictures/ or similar. Maybe
even move

/mnt/home/foo/Pictures/ to /mnt/home/foo/my_pics/

or

/boot/Pictures/         to /boot/my_pics/

so freedesktop.org can do whatever it wants to do with an empty folder
such as Pictures/ linked or not linked. IMO the first capital letter is
a nuisance anyway.
