Subject: [PATCH] [IMP] purchase: set scheduled date of lines

Commit 4326d864 removes the inverse function of the `date_planned`. This
is necessary to avoid unexpected changes of the scheduled dates.
However, this removes the ability to set the scheduled dates of all
lines at once.

This commit introduces back the functionality thanks to a new button.
This way, the functionality remains without unexpected behavior.
