Reminder emails for KPI providers

[mzur]

Here is a feature idea: If a KPI provider should enter information manually, send them a regular (e.g. monthly) automated reminder email with a link to the entry form.

This feature was pushed back as 'nice to have' feature, however I see where it is helpful to the user. I can't promise any ETA, but it should be included in a later version
