Updated release notes.
Google Test framework initial integration with Gradle. It includes plugin, tests, docs and sample.
Play design doc - improve formatting of code blocks

The code block for "All Scala source sets in a Play application are joint-compiled" was previously unreadable as it didn't have any indentation or formatting. This also adds syntax highlighting to all code blocks
Fixed broken user guide sample int test
Bump wrapper to build gradle with latest nightly
Pull ‘build’ task up into LifecycleBasePlugin
Cleaned up wiring of play test tasks into ‘check’ (somewhat)
Wire the native test tasks into the ‘check’ lifecycle task
Add a spin assertion around the check that the release notes contain the same number of fixed issues as the data feed.

My theory here is that we are probing the list part way through the insertion op.
Fixes for some racey tests.

Merge pull request #366 from benmccann/patch-1

Play design doc - improve formatting of code blocks
Modified the build output layout for play applications to be simpler and more consistent
Simplified construction of JUnitXmlTestExecutionResult in tests
Fix of ```test.testLogging.showStandardStreams = false```
The setter was ignoring the flag, so it wasn't possible
to disable standardStreams using this setter.

The following sample easily demonstrates the problem with Gradle 2.2.1+:

```groovy
test {
    testLogging {
        showStandardStreams = false
    }

    // this prints true no matter what value you actually will use in assignment
    println("In-tests logging configured: ${project.test.testLogging.showStandardStreams}")
}
```
Create the static builder in ModuleVersionSelectorParsers only once instead of doing the costly reflection every time
Minor tweak to string processing
