Ensure order in the galaxy... I mean the imports

This patch sorts the imports:

1. std imports
2. external crate imports
3. own module imports

In three blocks, each alphabetically (with is also enforced by rustfmt).

As well as it prefixes the imports of own modules with crate::

This is just a quality-of-life patch :-)
