Rebalance Java and Common

Remove duplicated rules from `Java`, and move those that make sense to
`Common`. This way both rules files can be used together, and the
settings for more generic files like shell scripts, JSON, YAML can be
more easily applied to other types of projects.

Add settings that ensure Windows based scripts (`.bat` and `.cmd`) end
with CRLF.
