Enable git hook protection in master branch

README.md

1. git config --global init.templatedir '~/.git-templates' - so git will copy all templates into new or cloned repository
2. mkdir -p ~/.git-templates/hooks
3. touch ~/.git-templates/hooks/pre-commit
4. chmod +x ~/.git-templates/hooks/pre-commit
5. Update ~/.git-templates/hooks/pre-commit with the following content

BRANCH="$(git rev-parse --abbrev-ref HEAD)"

MASTER_CHECK_ENABLED="$(git config --get custom.hooks.mastercheck || echo 'true')"

if [ "$BRANCH" = "master" ] && [ "$MASTER_CHECK_ENABLED" != "false" ]; then
  echo "\033[0;31mCommit failed!"
  echo "You can't commit directly to master branch.\033[0m"
  echo "Run \`git config custom.hooks.mastercheck false\` to disable the check for current repo."
  exit 1
fi

6. Run git init in all repos you have already cloned. Done! This will not work if particular repo already has pre-commit hook. In that case just drop in bash part into existing script.
