Polish whitespace and comments in pom files

- Convert spaces to tabs on -ftp/pom.xml

- Normalize multi-line comments to fit the following style:
    <!--
        depend explicitly on 2.0 in order to pick up the new
        release:update-versions goal
    -->

- Revert some of the formatting that the Maven release:update-versions
  goal forced on us. After it failed to perform its duties during the M7
  release, it appears we will not be using it anymore.
