Added support for specifying closures as renderers for the HTML "dependency to license" report of "downloadLicenses"

Hi all,

I added support for specifying closures as renderers for the HTML "dependency to license" report of "downloadLicenses".
Other useful changes are:

• DependencyMetadata now carries the complete POM information, useful in the custom renderers.
• The report is now sorted in alphabetical order.

With the new patch, users can specify something like the following:

downloadLicenses {
....
        report.html.dependencyToLicenseTableHeadRenderer = { table ->
            table.tr {
                th(){ h3("Dependency") }
                th(){ h3("Dependency artifact id") }
                th(){ h3("Dependency version") }
                th(){ h3("Jar") }
                th(){ h3("Dependency Url") }
                th(){ h3("License name") }
                th(){ h3("License text URL") }
            }
        }

        report.html.dependencyToLicenseTableRowRenderer = { table, depMetadata, license ->
            table.tr {
                String[] gav = depMetadata.dependency.split(':')
                td(depMetadata.dependency, class: 'dependencies')
                td(gav[1], class: 'dependencies')
                td(gav[2], class: 'dependencies')
                td(depMetadata.dependencyFileName, class: 'licenseName')
                if(depMetadata.url){
                    td(class: 'url') {
                        a(href: depMetadata.url, depMetadata.url)
                    }
                } else {
                    td('no url available', class:'url')
                }
                td(license.licenseName, class: 'licenseName')
                td(class: 'license') {
                    if (license.licenseTextUrl) {
                        a(href: license.licenseTextUrl, license.licenseTextUrl)
                    }
                }
            }
        }

}

The code works successfully.

I wasn't able to set the closures as "@input" parameters of the task due to the fact that gradle then executes them with no arguments as a result of an "unwrap" phase at setup time, leading to the following exception:

groovy.lang.MissingMethodException: No signature of method: nl.javadude.gradle.plugins.license.LicenseReporter$__clinit__closure8.doCall() is applicable for argument types: () values: []
Possible solutions: doCall(java.lang.Object, java.lang.Object, java.lang.Object), isCase(java.lang.Object), isCase(java.lang.Object), findAll(), findAll(), findAll(groovy.lang.Closure)
    at org.gradle.api.internal.tasks.DefaultTaskInputs.unwrap(DefaultTaskInputs.java:111)
...

Maybe you know how to correctly set them as input parameters.

Looks like I've broken some unit tests. Sorry.
Also, please note that I tested the plugin under Gradle 1.10

Cheers,
