ISO week dates can now be entered at the date prompt.
The ISO week of each day is displayed in the agenda.
New jumping commands like `43 w' quickly switch the agenda
to a certain week.
This system works by configuring a variable that contains a list of
all available modules. These will automatically be loaded when the
first buffer is turned into org-mode, or when a global command
is run that needs org-mode code available (such are
org-store-link.
In particular, this implements default dates for deadlines and
scheduled items, taken from previously existing deadline/scheduled
timestamps in the same entry.
Also we fix two minor bugs.
To save time, we don't re-initialize the list of projects/files each
time a file is published. But if people want to publish a file that
they just created, this file is not part of any project until the
list of project/files has been re-initialized.
If the file is not part of a project and should be, then the user
can tell so.
There mechanisms were asked for by Wanrong Lin and Reiner Stengele and
have the goal to make sure the new deadline/scheduled/time is in
the future, and may be chosen relative to the current date.
