INT-2512 - Upgrade to Gradle 1.0-rc-1

* Upgrade Gradle Wrapper
* Remove deprecation warnings
* Fix Sonar Build

Depends on: https://github.com/SpringSource/gradle-plugins/pull/1

INT-2512 - Improve declaration of optional and provided dependencies

INT-2512 - Reverted Bundlor Plugin Version Number.
With that change the Spring Integration specific part of the code changes is decoupled from the Bundlor pull request:

https://github.com/SpringSource/gradle-plugins/pull/1
.
Once the Bundlor plugin is updated and released, I can bump the version number (Only then, though all deprecation warnings will be gone).

INT-2512 - Code Review

**Do we really want to add mavenlocal() permanently? I usually add it locally when I need it**

Sorry my bad. Forgot to remove my local addition.

**snapshot?**

The Bundlor plugin relies on Snapshot releases for the Gradle plugin (I reverted the DocBook version).

**mixed leading tabs and spaces**

Removed every single leading space. Unfortunately, there were lots of spaces. Took a while. I hope this looks much better.

**Why are we removing this? Don't we need a local install any more?**

The Maven install logic is now handled by the customized/extended "maven" plugin in **publish-maven.gradle**. This is how Chris has set it up for the Spring Framework.

INT-2512 - Remove mavenLocal()

Change 'build/jacoco.exec' to '${buildDir.name}/jacoco.exec'.
