[Kimchi-devel] [PATCH 3/4] Remove unnecessary import aliases

In order to make the code less ambiguous and more consistent, only use
import aliases (i.e. 'import ... as ...') if it is needed to solve a
conflict in the imported class names. For example, if there is a class
named 'kimchi.model.file', the following import statement would lead to
an anbiguity when trying to use the type 'file' (because of the built-in
type 'file'):
from kimchi.model import file
One of the solutions to this conflict would be to use an alias, e.g.:
from kimchi.model import file as kfile
Unless it is necessary, do not use import aliases.
