[Proposal] PHAR Distribution about jigsaw

[damiani]

No plans for this at the moment, but if you run into dependency conflicts when installing globally via Composer, you can always install Jigsaw locally to your project.

I too would like to see a phar distribution; having it installed globally via composer causes issue on my machine because it has conflicting requirements with some other globally installed tools - having it boxed as a phar would solve that.

I was able to build a package myself here are some instructions on how I did it:

### First you need to download the lastest of phar
### Install phar-composer
php phar-composer.phar --version
chmod 755 phar-composer.phar
sudo mv phar-composer.phar /usr/local/bin/phar-composer

### Build and Install the jigsaw project
phar-composer install  tightenco/jigsaw
