Add event and event series entities

[pacodelcastillolopez]

Adding two new ANET entities: event series and events.

• They have a host organization that can be any organization in ANET and an admin organization which needs to be managed by the user creating the event series or event (superuser or admin).
• Events have also a location, start date and end date and are searchable.
• Objectives can be linked to events.
• Reports can be associated to events. When creating from the Event page it will inherit its location and objectives, the date of the report has to be within the start and end date of the event.
• Events will be displayed in the organization, location and objective pages. In addition, the objective page shows an event matrix.

Closes AB#1064, AB#1172, AB#1173
