Add CSS for figures.

Example shortcode usage:

{{< 
    figure src="/img/0005/eclipse_companion_shared_lib_error.png"
    link="/img/0005/eclipse_companion_shared_lib_error.png"
    caption="Eclipse Executable Launcher Error message."
>}}

Note:

Maybe adding options to add custom JS and CSS code would be a good idea for the future... See e.g. here.
