Chamilo LMS

When managing hundreds of skills, the current hierarchy lacks information to be able to link or search specific skills.
Adding tags would allow for the use of a user-defined taxonomy.

Add tags to add to skills (skill creation/edition form) through extra_fields and add a "search by tag" option in the skills management screen.
Also support a "tags" column in the CSV skills import feature.

To use with extra fields, the SKILL_FIELD_TYPE needs to be added to the ExtraField.php entity.
