Remove complex import order

Google's style guide changed its complex rules to be much simpler: all
static imports, then all non-static imports:

https://google.github.io/styleguide/javaguide.html#s3.3.3-import-ordering-and-spacing

google-java-format will also understand this order.

Change the Eclipse project settings and .importorder file, and reorder
everything.
