ENH: Add SetupForDevelopment and first git hooks

- SetupForDevelopment is a bash script that will setup the git
environment for the user, by running setup scripts in SetupScripts
directory.
- SetupGitUser will assure that a conform name and email adress
are configured.
- SetupGitHooks will copy git hooks in the .git/hooks directory
- SuggestGitTips will suggest useful tips to configure git
- prepare-commit-msg is a git hook which will display the standard
prefixes that can be use for the commit summary
- commit-msg will ensure the commit message follows those standards
as well as some other basic rules

In the future we will incorporate KWStyle to check the code style
in the git pre-commit hook.
