ui: Allow users to provide a CSS file to customize styling
- Don't include the file if it does not exist to avoid a 404 error every time a
page it loaded.

- Load the file from a know path under the already known custom static path.

Tests:

- When the user.css file is created, it added to the web page. It is prioritized
over the main.css with CSS cascading rules.

- When the user.css file does not exist on the filesystem, it is not added to
the web page.

- When custom static directory (/var/www/plint) does not exist on the
filesystem, a debug log message is printed that this directory is not served.
