Added a gradle build tool plugin

* Enhanced gradle plugin to parse tasks from a quick execution of the tool
* Added a duplicated function for gradlew completion that uses gradlew internally. Builds like Gradle itself (built with Gradle) are sensitive to being run with a matching gradlew version.
* Fixed broken caching of gradle task names. Added - and -- argument completions.
