feat(web): add the ability to use the original file name

[Jeconias]

Why

This feature allows the use of the docsify-edit-on-github plugin which needs the original file name in the path.

What

Added WEB_FILE_NAME as an option in the configuration.

How to use

If you add webFileName to .c4builder, each .md will be named exactly the same as the defined value. The default value is HOME, see.

This feature ability to use the original file name and remove the default value (HOME).

NOTE: To maintain compatibility with previous versions of links, add a new option in .c4builder:

{
  "webFileName": "HOME"
}

Example

with-home.mov

With this feature and webFileName not defined or empty:
