OpenQuake Engine 1.4.0

[Daniele Viganò (@daniviga)]

• Fixed debian/control: add missing lsb-release to build deps

[Matteo Nastasi (@nastasi-oq), Daniele Viganò (@daniviga)]

• Fixed dependencies version management

[Matteo Nastasi (@nastasi-oq), Daniele Viganò (@daniviga)]

• Add binary package support for both Ubuntu 12.04 (Precise)
  and Ubuntu 14.04 (Trusty)

[Michele Simionato (@micheles)]

• Removed the SiteModel table: now the association between the sites and the
  site model is done by using hazardlib.geo.geodetic.min_distance

[Daniele Viganò (@daniviga)]

• added authentication support to the 'engineweb' and the 'engineserver'

[Michele Simionato (@micheles)]

• the aggregate loss curves can be exported in CSV format

[Matteo Nastasi (@nastasi-oq)]

• added 'outtypes' attribute with list of possible output types for
  each output item in outputs list API command
• added '/v1/calc//status' API command
• added 'engineweb' django application as local web client for oq-engine

[Michele Simionato (@micheles)]

• Renamed the maximum_distance parameter of the risk calculators to
  asset_hazard_distance, to avoid confusion with the maximum_distance
  parameter of the hazard calculators, which has a different meaning;
  is it an error to set the maximum_distance in a job_risk.ini file
• Added to the API an URL /v1/calc/:calc_id/remove to hide jobs
• A new key is_running is added to the list of dictionaries returned by
  the URL /v1/calc/list
• Replaced the mock tests for the engine server with real functional tests
• Added a resource /v1/calc/:calc_id/traceback to get the traceback of a
  failed calculation
• Now the logs are stored also in the database, both for the controller node
  and the worker nodes
• Bypassed Django when deleting calculations from the database: this avoids
  running out of memory for large calculations
• Fixed an issue in the scenario calculator: the GMFs were not filtered
  according to the distance to the rupture
• Now critical errors appear in the log file
• Added a --run command to run hazard and risk together
• Fixed bug in the event based calculator; in the case
  number_of_logic_tree_samples > 0 it was generating incorrect hazard curves.
  Also improved (a lot) the performance in this case.
• Fixed a tricky bug happening when some tectonic region type are filtered
  away.
• The event based risk calculator now save only the non-zero losses in
  the table event_loss_asset.
• Added a CSV exporter for the Stochastic Event Sets, for debugging purposes.
• The GMF CSV exporter now sorts the output by rupture tag.
