HaroldMills/Vesper: v0.4.4

This release:

• Adds a new coarse classifier, MPG Ranch NFC Coarse Classifier 3.0, that annotates clips created by the Old Bird detectors as calls or noises. The new classifier performs considerably better than version 2.0.

• Updates MPG Ranch NFC Coarse Classifier 2.0 to version 2.1. The new version should label clips exactly as the old one did. It uses the version of Keras that is now built into TensorFlow rather than the separate version, however, eliminating dependence on the separate keras package.

• Increases the speed of clip album page loads by transferring clips from the server to the client in batches instead of one at a time.

• Increases the speed of the Delete Clips command.

• Updates Vesper to use the most recent version (2.1) of Django.

• Fixes broken archive data import drag and drop operations, issue #146.

• Adds a new time interval spectrogram clip view overlay.

• Adds a choice of marker type to the time-frequency point overlay.
