Add DSL support for JaCoCo Line Coverage column via 'jacoco' method

[drwoods]

Passed build.
Ran embedded server and installed JaCoCo 2.0.1 plugin to verify the following Job DSL -

listView("TestView") {
  columns {
    status()
    weather()
    name()
    lastSuccess()
    lastFailure()
    lastDuration()
    jacoco()
  }
  jobs {
  }
}

Generated a List View that I could then add the above job to and see that the view included the column and the View XML was correct -

<?xml version="1.0" encoding="UTF-8"?>
<hudson.model.ListView>
  <name>TestView</name>
  <filterExecutors>false</filterExecutors>
  <filterQueue>false</filterQueue>
  <properties class="hudson.model.View$PropertyList"/>
  <jobNames>
    <comparator class="hudson.util.CaseInsensitiveComparator"/>
    <string>TestDSL</string>
  </jobNames>
  <jobFilters/>
  <columns>
    <hudson.views.StatusColumn/>
    <hudson.views.WeatherColumn/>
    <hudson.views.JobColumn/>
    <hudson.views.LastSuccessColumn/>
    <hudson.views.LastFailureColumn/>
    <hudson.views.LastDurationColumn/>
    <hudson.plugins.jacococoveragecolumn.JaCoCoColumn plugin="jacoco@2.0.1"/>
  </columns>
  <recurse>false</recurse>
</hudson.model.ListView>

When the updated plugin is used in a job to add the jacoco column to the List View, it causes the build to be marked as Unstable due to -
Warning: (script, line 241) version 1.0 or later of plugin 'jacoco-column' needs to be installed

Updated commit that fixes the plugin id, which removes the Warning so the resultant build will now be marked Stable.
