change: open deployment new page directly in summary section

Previously it opened the default section, which is "Nodes" for
deployments.
fix: re-enable section accordion toggling screwed up with 2fb5222
new: enable publish/unpublish functionality
new: for published modules show publication date in summary section
fix: redirect on user creation

Note: this is a server bug though.
fix: do not require commit message for configuration save action
fix: redirect to root if location header expected but not found

This solves the redirection to /null after saving the configuration, but
should be fixed in the server to return the correct location header.

The same seems to apply for PUT and DELETE requests on all root resources
(user, configuration, root project...).
change: auto-remove alerts after 5 secs

At the same time, the code to prevent the same alert to be added several
times is removed, since it makes less sense if they automatically
disapear.
fix: deletng resources (users, modules) whose name begins with 'new'
refactor: allow call fn after askConfirmation modal returns OK button

This allow to easily prepend a modal confirmation to any code.
new: ask for confirmation before publishing or unpublishing modules
new: auto dismiss also alerts present on page load (see b4884a5)
fix: tests for modules after having added info about publication
fix: table expectations with new :content/map for :cell/timestamp
