Subject: [PATCH 1/2] Fixed ECS example compilation issues

If you paste the old 'Using Bevy ECS' sample code and try to compile it you will get error messages
 - system() is not being called for the movement system in the scheduler
 - The movement systems Query is not mutableable which the rust compiler doesn't like

This small commit fixes that so that new users don't have this issue when trying to lean from the samples.

Subject: [PATCH 2/2] Undid ECS 'use' format change

Noticed that I accidentally changed the use format from 'bevy_ecs' to 'bevy' which seems to be the standard for the crate examples, So reverted that change.
