acknowledgements 7.x-2.12

- better users selection while editing a content
- now a notification email can be sent to selected users and roles
while creating a new content.
- when a user or role is added to an old content, email is sent only
to new users/roles
- views integration: user and date fields added.
- PATCH: attached to project page you find a patch that removes unwanted
text from content page. The file must be in the module directory, then
you can apply the patch with "patch <rem_email_msg.patch".
- NOTE: better views integration is planned for next release (probably 3.0)
