BigBlueButton Chamilo plugin
============================
This plugin allows you to have videoconference rooms in each course.
It requires you to have a BigBlueButton videoconference server installed on another server (ideally).

## Migrating from Chamilo LMS 1.9.x to 1.10.x
For Chamilo 1.10.x, the Videoconference plugin has two new settings options: *Enable global conference* and *Enable conference in course groups*.

ALTER TABLE plugin_bbb_meeting ADD voice_bridge int NOT NULL DEFAULT 1;
ALTER TABLE plugin_bbb_meeting ADD group_id int unsigned NOT NULL DEFAULT 0;
ALTER TABLE plugin_bbb_meeting ADD user_id int unsigned NOT NULL DEFAULT 0;
ALTER TABLE plugin_bbb_meeting ADD access_url int NOT NULL DEFAULT 1;
```

```sql
CREATE TABLE plugin_bbb_room (
    id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
    meeting_id int(10) unsigned NOT NULL,
    participant_id int(11) NOT NULL,
    in_at datetime NOT NULL,
    out_at datetime NOT NULL,
    FOREIGN KEY (meeting_id) REFERENCES plugin_bbb_meeting (id),
