Moved commands into code blocks to fix rendering and improve readability

This:

    <project home> $ cp rider-auto-common/src/data/message1.xml <JBoss Fuse home>/target/placeorder

was rendering as:

<project home> $ cp rider-auto-common/src/data/message1.xml <JBoss Fuse home>/target/placeorder

Which is incorrect due to the angle bracketed text being omitted. The easy fix is to put the commands in code blocks. I think this also slightly improves readability.
