Improve composer name

[igorw]

"PHP-Log-Class/PHP-Log-Class" is not a really good name. For one, the name "class" in a project name really makes no sense. What if you add a second class, or otherwise evolve it? Then it's no longer a class. Besides, the fact that it's a class is not relevant for the name.

I'd also choose a vendor name that makes more sense.

I don't know, maybe something like joeynoh/log?

Also, you did not add your project to Packagist. Please fix the name before you do.
