Remove use of '>' which cause javadoc errors

Tested with Java 8 and "mvn javadoc:test-javadoc".  Eliminates errors in other plugins such as multiple-scms-plugin,
such as:

    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.8:jar (attach-javadocs) on project multiple-scms: MavenReportException: Error while creating archive:
    [ERROR] Exit code: 1 - target/checkout/target/generated-sources/taglib-interface/org/jenkinsci/plugins/multiplescms/FormsTagLib.java:21: error: bad use of '>'
    [ERROR] *     The submission can be data-bound into List<T> where T is the common base type for the describable instances.
    [ERROR]
    [ERROR] target/checkout/target/generated-sources/taglib-interface/org/jenkinsci/plugins/multiplescms/FormsTagLib.java:23: error: bad use of '>'

No shebang

After https://github.com/github/linguist/pull/2861 we should not need the shebang for syntax highlighting.

Re-introduce a reference to the setup administrator password in the logs

This makes if possible for users without access to filesystems, like those
running Jenkins masters in Docker containers (unmapped jenkins_home) to still be
able to successfully use Jenkins 2.0

This commit also fixes an errant reference to "security token" which we no
longer use in the beginning of the Getting Started wizard, opting instead for
"administrator password"
