composer integration

Please add these integration for easier forking :)

For the moment I use these to add my fork into composer.json:

• "repositories" section :
  { "type":"package", "package": { "name": "wpackagist-plugin/keyring", "version": "<custom_version>", "type": "wordpress-plugin", "source": { "type": "git", "url": "git@github.com:<my_vendor_name>/keyring.git", "reference": "tags/<custom_tag>" } } }
• with this line in "require" section :
  "wpackagist-plugin/keyring": "<custom_version>"

With these PR it coult be :

• "repositories" section :
  { "type":"vcs", "url": "git@github.com:<my_vendor_name>/keyring.git", } }
• require section :
  "beaulebens/keyring": "dev-<my_patch_branch>"
