Email attachment feature.

From 2.1 forwards, LimeSurvey will officially support adding file attachments to emails sent by the system.

The following templates support adding attachments:

Attachments can be added at the bottom of the email template editing interface. Email attachments are uploaded on a per survey basis.

To decide if an attachment should be sent on an individual basis it is possible to add a relevance equation to each attachment.

All functions supported by the Expression Manager can be used, as well as token attributes if the survey uses tokens.

In case of a notification or confirmation template it is also possible to use question codes used in the survey.

When a file can not be found on the file system, the email will be sent without attachment.
Exporting / importing a survey does not export the uploaded files. The settings for attachments will be maintained, as will the relevance equations.
