This at least gives admins the chance of doing this if they want to.

Improved the wording for the Upload CSV page, especially in the case of institutional admins. Fixes #2214.

Previously, Institutional Admins were given links to pages they couldn't edit.

Instead, generate a list of users who we could not send e-mail to, and display this to the uploaded, with more detailed reasons in the server error log.

* Force password change: if checked, users are forced to change their password on next log in. This was mandatory before, now people uploading CSV files can choose.
* E-mail users about accounts: if checked, users are sent an e-mail about their new account. This was never an option before and never happened, now it is on by default.

We send a slightly different e-mail based on whether the user needs to change their password or not. This affects the Add User script a tiny bit.

Added a line of descriptive text to the page to help admins understand what will happen on this page.

Corrected a language string when the password for the new user is in invalid form.

The name is largely irrelevant as it's only the creator of the file.
