Add Composer.gitignore for composer packages

Libraries/Projects using [Composer](http://getcomposer.org) for dependency management should include a `.gitignore` file like this.

It ignores the vendor folder which Composer uses for dependencies, classmaps and others. Composer keeps git repositories in this folder so it is cleaner if it is ignored.

[`composer.lock` should not be ignored.](http://getcomposer.org/doc/01-basic-usage.md#composer-lock-the-lock-file)

> Commit your application's composer.lock (along with composer.json) into version control.

> For your library you may commit the composer.lock file if you want to. This can help your team to always test against the same dependency versions. However, this lock file will not have any effect on other projects that depend on it. It only has an effect on the main project.

Make Python .gitignore directory entries match only directories

This commit also alphabetizes the distribution/packaging section after
separating the directory entries from the file entries.  I left alone
a few entries that I'm not sure about (i.e. *.egg and the
"Mr Developer" section).

*.suo files are binary, user specific files generated by Visual Studio with some user configuration information, thus, don't need to be versioned.
