[PHP] core.acp_attachments_add

[vipaka]

Identifier: core.acp_attachments_add
Prosilver Location (if applicable): Honestly this file should probably have 2 or 3 event dispatch locations, one for the php loops, one for the template loops, etc.
Explanation: Mods like the points mod require a new value be added individually for each attachment type, so that they can be adjusted individually. Without any way to add php or template variables to this file, that is impossible.
