Gradle Bash Tools

## Features:

provides shorthand gr for running Gradle
uses Gradle wrapper when available
invokes Gradle correctly from any subdirectory of a project (e.g. when you are under src/main/java)
supports auto-completion for projects and tasks across multi-project hierarchies
- supports leading colon to select subprojects / tasks of root project

How to install and use it:

Put bashCompletion.gradle under ~/.gradle/init.d/ (Create this directory if it does not exist)
Put gradle-bash-tools.sh somewhere and reference it in ~/.bash_profile with source /path/to/gradle-bash-tools.sh
Completion targets need to be generated / updated by calling gr bashCompletion for the specific project
