Save report to markdown / iframe

[Marlon154]

As: a user
I want: to have a button to save the current report. It shall be store in the file and there is no need for addition APIs calls.

This will be handy to archive ones old reports and ensure, that the data is always avaible and not dependent on Toggl anymore.
