Add support for file links

[jjmdg]

Support for links like \share\directory\file.pdf and file:///\share\directory\file.pdf would be nice (especially for use in a business context).

Not possible: http://stackoverflow.com/questions/5246292/open-local-folder-from-link
Producing downloadable links (could be a solution) is probably not in scope for linkify

[jjmdg]

Could still be implemented so that the user can easily copy the address and paste it to his system. It works like that in Confluence for example.

Problem with not-working file:// links in browsers easily solved via extensions or via pre-configured settings:

• Firefox settings: https://stackoverflow.com/a/13083926/1395757
• Firefox extension: https://addons.mozilla.org/en-US/firefox/addon/local-filesystem-links/?src=search
• Chrome extension: https://chrome.google.com/webstore/detail/local-explorer-file-manag/eokekhgpaakbkfkmjjcbffibkencdfkl

So linkifyjs must only mark file:///home/user/file.txt text as <a href> links, all other work will be done on browser and system side. If we don't want to enable it by default, make this optionally.

At now library already support file:// links with two slashes, but fails with linux-style links contains 3 slashes: file:///home/user/file.txt - here is example:

> const lfy = require('linkifyjs');
undefined
...
> lfy.find('file:///test');
[]
> lfy.find('file://test');
[ { type: 'url', value: 'file://test', href: 'file://test' } ]

So, at first, we must fix the bug with file:///test.

Since RFC8089, both the file:/etc/motd and the file:///etc/motd versions are in use for local URIs.

I ran into this issue as well. Any idea when V3.0 will be ready?

Links that begin with file: are now supported in the latest Linkify v4.0
