Scheduled reports: fine-tune the way we attach reports

[joebordes]

It would be a bit of work to:
- find the hardcoded email
- move it to a template (something like this)
- add some special merge variables for the links and attachments (like $context in the link above)

but it shouldn't be that complicated.



also note that if format is URL it does not send the attachments (I think)
