* Create composer.json for instalation with composer
The installation is much simpler with Composer and https://github.com/RobLoach/component-installer
After merged you can test it:
```
composer config repositories.zenorocha-clipboardjs vcs "https://github.com/zenorocha/clipboard.js/"
composer require zenorocha-clipboardjs:dev-master
```
Before merged you can test using my git fork.
Composer creates a "components" folder that contains the "clipboardjs" whith all files spec in "files" of composer.json.
You can then register the "package" at https://packagist.org In this way the installation would be simpler:
`composer require zenorocha-clipboardjs:dev-master`
* Remove icon
blur() results in a loss/reset of keyboard focus, meaning keyboard users usually get thrown right back to the start of the page. Instead, this moves focus back to the trigger (which had the focus when the trigger was activated).
As with the proposed fix in https://github.com/zenorocha/clipboard.js/pull/418 this obviously results in the focus styles (like the default outline, unless suppressed) being applied to the trigger (see the related PR for rationale and future fix using `:focus-ring`)
