New way to download a single event

- The event export buttons have been unified into a single download as... button
- clicking it loads a popup with all of the export formats
- added snort, suricata, text dump to the export options
- added the option for an extra setting for some exports (such as including non IDS flagged attributes, encoding attachments)
- easily extendable system

- moved the hidden popup divs into the general layout, can be easily reused anywhere

- removed the auth refresh option that was re-enabled recently as it seems to sometimes cause issues

- text exports now allow "all" to be specified as type, which will dump all attribute values that the user can see
- text exports now allow restricting the results based on event id
Update to the automation page

- new parameters for the text export explained
Remote attribute deletion removed

- Deleting attributes on connected MISP instances can cause serious performance issues on multiple interconnected instnaces, temporarily removed
- Version number incremented
