Issue #1062: Add tools/pre-push-recommended.sh.

#!/bin/sh

# We recommend you run this as a pre-push hook: to reduce

# review turn-around time, we want all pushes to run tasks

# locally. Using this hook will guarantee your hook gets

# updated as the repository changes.

#

# This hook tries to run as much as possible without taking

# too long.

#

# You can use it by running this command from the project root:

# `ln -s ../../tools/pre-push-recommended.sh .git/hooks/pre-push`

# Descriptions for each gradle task below can be found in the

# output of `./gradlew tasks`.
