1.0 release of Liberty Gradle Plug-in

[jgawor]

Create the first release of the Liberty Gradle plug-in.

[jgawor]

• Created tag for the release: liberty-gradle-plugin-1.0
• Created documentation that talks about publishing snapshots and making releases.

• The release artifacts are now staged at: https://oss.sonatype.org/content/repositories/netwasdev-1008/ and ready to be tested.

    repositories {
        mavenCentral()
        maven {
            name = 'staging site'
            url = 'https://oss.sonatype.org/content/repositories/netwasdev-1008/'
        }
    }
    dependencies {
        classpath 'net.wasdev.wlp.gradle.plugins:liberty-gradle-plugin:1.0'
    }

Created a new RC with updates for #38, #39 and #40. The release artifacts are available at: https://oss.sonatype.org/service/local/repositories/netwasdev-1020/content/

    repositories {
        mavenCentral()
        maven {
            name = 'staging site'
            url = 'https://oss.sonatype.org/service/local/repositories/netwasdev-1020/content/'
        }
    }
    dependencies {
        classpath 'net.wasdev.wlp.gradle.plugins:liberty-gradle-plugin:1.0'
    }

Testing was successful, so I created liberty-gradle-plugin-1.0 tag, published a GitHub release, and promoted the artifacts to Maven central.
