0.9.0

Features & Changes:

• Channel-lists have been removed. Extra channels (if supported by the ISM
  band) are now managed by LoRa Server configuration.

Bugfixes:

• On editing a gateway, disable the MAC input field (as this is the unique
  identifier of the gateway).
• A pagination regression has been fixed (#82).

Note: when upgrading to this version with --db-automigrate /
DB_AUTOMIGRATE set, channel-list data will be removed.
