Drag files in to vmd

[maxkueng]

Would be cool if it was possible to drag files from the desktop or file manager in to vmd.
When vmd receives a file it would automatically render the new file and start watching it.
The functionality to change the file inside a vmd window is already implemented.

Bonus features

• Dropping a file while holding the shift key would open the dropped file in a new window.
• Ability to drop an URL to a markdown file and render it.
