Add package to packagist

[matatirosolutions]

In line with #39 once a composer.json file exists please add this project to packagist to make inclusion in project simpler.

[ejsexton82]

I previously added a yodarunamok/fxphp package to Packagist.org, but I pointed it to my own ejsexton82/fxphp repo because the composer.json file was set incorrectly.

I felt this was misleading, though, and I have repointed yodarunamok/fxphp package back to the actual yodarunamok/fxphp repository. If you are looking to continue using the yodarunamok/fxphp package, please use the following command:

$ composer require yodarunamok/fxphp:dev-master

I apologize for any inconvenience this may cause. If the owner of this repository would like to take over the yodarunamok/fxphp package on Packagist.org, just let me know.

If you are interested, we are currently using and maintaining a forked adatasol-tourtools/fxphp package and adatasol-tourtools/fxphp repo:

$ composer require adatasol-tourtools/fxphp
