Robustness on entry point module loading
This patch add some robustness to the loading of the extra camera defined by the setuptool entry points.
- Use the same logging behaviour for
camera
andplugins
- Catch any exception, and not only
ImportError
For some reason, during the update from BLISS 1.9 to 1.10, i have to deal with pkg_resources.DistributionNotFound
, for optional cameras.
