Small typo in documentation

[nigelcharman]

Just a minor issue, but it caught me out first time.

In the README, for 1.3.1 and above, the text "apply plugin: 'jmeter'" should be in the code block.

Currently showing:

If it is 1.3.1 and above apply plugin: 'jmeter'

    buildscript {
        repositories {
            mavenCentral()
        }
        dependencies {
            classpath "com.github.kulya:jmeter-gradle-plugin:1.3.1-2.6"
        }
    }

Should be:

If it is 1.3.1 and above

apply plugin: 'jmeter'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath "com.github.kulya:jmeter-gradle-plugin:1.3.1-2.6"
    }
}
