Why are you committing the composer phar ?

[stof]

This creates issues with IDEs when using PhpStorm to work on Packananlyst for instance, because it finds the class definition for composer files multiple times:

• in vendor/composer/composer where composer got installed as a dependency
• in vendor/mouf/mouf/composer.phar because PhpStorm is smart enough to analyze phars

There are ways to make it ignore the phar, but this practice looks weird (and your phar is old btw, as it is from December 2014)
