First public beta

The following features are currently implemented:

• INDI server management. Start, stop, connect to INDI, select drivers to load, and save profiles for future usage.
• Sequences: exposures, filter wheel, change camera properties, and run shell command can be added to a sequence. Sequences can be copied to act as "template".
• Camera: allow to get a preview of the field of view, exposure settings, histogram, and ROI selection for focusing.
• Image browsing: you can view images shot by a sequence, preview them in your browser, or download the original FITS file.

You can also find a ready to go Raspberry Pi image.

note: please don't use the "Source code" files in this release, as they are incomplete (github doesn't include the submodules). You should use binary packages, or if you really want the sources, clone the repo with the submodules.
