Make setup.py executable
Import * from scancam
Remove leftover badly named init file
Update module import names to reflect packages
Find scancam.conf in /etc/

That is where the distutils installer puts it.

However, this is pretty Linux-centric and we should look at another way to
handle it.
Use self camera reference instead of global

The global was working becuase the script and library were previously together
update module import name to reflect new arch
Fix mysterious indent and location of exception
Delete empty obsolete file
fix legacy global calls

These accidentally worked when the scancam lib and script functionality lived
together. Now that the scancam instance is no longer in with the class
definition, it shows up that it was calling the global instead of self.
