The variable GIT_DIR has been removed in modern git distributions.

* Alignment of variables and comments
* Add/remove spaces when needed
* Enforce spaces around '*' and '&' of reference and pointer variables
* Remove redundant semicolons
* Break line between function return type and function definition
* Enforce position of boolean operators, making multiple-line boolean expressions easier to read

Replace many 'add' options by 'force' option for new line and space: if two ore more empty lines (or spaces) exist, modify them to make sure there is just one empty line (or space).

Add option to enforce a break line between namespace/class and brace character.

Add several more options to enforce space around operators/parenthesis/bracket etc.

Enforces license header and the rest of configuration options. To enable it,
manually run SetupForDevelopment.sh and enable uncrustify during configure.
Also provided is default configuration file to be consulted when a new
option is needed. This file has explanations for all the options.

Also, some source code files have been modified to prevent ugly auto-reformatting.

* specify the algo preceded by a dash such as -algo
  with algo=[sha sha1 sha224 sha256 sha384 sha512 md5]

* specify the path to a folder or a file
    - if file: create key file at dest_path (=path by default)
    - if folder: go through all sub-directories and create key files at
      dest_path (=path by default) based on sub-directory architecture

/!\ WARNING /!\ : Won't work has expected if a directory contains dot!
  -> Because we identify a file if it contains dot for now

Make sure that we don't run into an error when uncrustify
is disabled, by providing info on how to set it up.

Also allow to skip uncrustify (not recommended).

Use config based on https://gist.github.com/mkroman/1372117

- Still need to edit the configuration file
- Removed example target for kwstyle

- 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.
