Add Composer support

[cmfcmf]

Composer is a package manager for PHP. This allows jQuery-Timepicker-Addon to be downloaded by putting "trentrichardson/jquery-timepicker-addon" into your own composer.json file.

{
  "require": {
    "trentrichardson/jquery-timepicker-addon": "~1"
  }
}

Please update the jqueryui dependency like you update it in component.json.

Notice that I had to set the jqueryui dependency to 1.10.2, because the versions before do not exist for Composer. So start updating the jqueryui dependency when you require jqueryui > 1.10.2

Hey @cmfcmf sorry for the delay, I can add this to the dev branch but could I ask your assistance. I have restructured the dev branch to utilize grunt, and so there is now a src and dist folder, where dist is the built files for use. Could you advise if there needs to be changes to the composure.json for this? (does it need to point to dist directory anywhere?)

Also if possible could you can you do a pull request for the dev branch?

I added the composer.json to the dev branch and updated the component paths to the dist directory.
