Support replacing current image on drag and drop

[zhanziyang]

Initially asked in #51 by @PrimozRome.

version 1.1.4 comes with a new prop: replace-drop

<croppa replace-drop></croppa>

turning on replace-drop mode will result in current image getting replaced by the new one on drag and drop.

• type: boolean
• default: false (By default you need to remove the current image to drop a new one)

@zhanziyang awesome, thanks for quick feature update.

@zhanziyang I tried the 1.1.4. and added replace-drop but you have a bug - the drag and drop with new attribute won't work over the initial image like this:

<croppa
    v-model="myCroppa"
    replace-drop>
    <img src="~/assets/img/profiles/1.png" slot="initial">
</croppa>

With a setup like this you need to first remove the initial image and then drag and drop will work. Can you fix this in next release?

Ok, I will look into it : )

@PrimozRome I can't reproduce your issue. I made a demo and it works fine here. Take a look. https://codepen.io/zhanziyang/pen/MONOeP

@zhanziyang thanks. I am not using your CSS and looks like I have problem with my CSS... Thanks for your effort.
