Upgrade to version 1.3.0

1. App Catalog: new ADMIN role. This role lets control if a resource could
be modified by an entity via REST API.

PubSub server to delete the same resource from Redis.
3. App Catalog: add colon (:) to the list of allowed characters to define resources identifiers.
4. App Catalog: display a custom view when a 404 error is raised.
5. App Catalog: fix bug in the components/sensors deletion procedure.
6. App Catalog: improve universal viewer when a component with lots of
sensors is clicked.
6. PubSub server: improve notification message content. Now includes more information according to the notification tipology (like location, sender, provider, ... )
7. Relational agent: when the location of an observation comes filled in, it is inserted in the relational database too.
8. Fix some minor bugs
Change owner and sentilo-catalog permission to ADMIN
Merge remote-tracking branch 'upstream/master'
