IE11 issue

[Olga Levanova]

Hi there,

File vue-a11y-dialog.js has 2 arrow functions and IE11 doesn't understand them. When I replace them with normal functions everything works perfect. Can you pleace fix this in repo? Thanks

Hey @OlgaLevanova, thanks for pointing this out.

I changed all arrow functions to normal functions to allow support for IE11. The release 0.5.1 has been published and you can upgrade.
