Custom email templates

[frensing]

Proposed changes

This change adds the possiblity to customize the e-mails send by the IDM through the theme folder. It is possible to provide a custom e-mail header and footer by providing the files themes/<MY_THEME>/email/_header.ejs and .../_footer.ejs.

It is also possible to customize the standard email templates. For example, the texts of the activation email can be changed by providing the file themes/<MY_THEME>/email/activate.ejs. It is recommended to copy the original file from views/templates/email/activation.ejs and customize then.
