Custom Admonitions

Add support for creating custom admonitions. That would include allowing users to add classes and change the icon. Something like this:

#+BEGIN_ADMONITION +CLASS=classname +ICON=filename.png
Lorem Ipsum
#+END_ADMONITION

Here is my reasoning for having these options specifically:

  • Classes
    Users could utilize classes provided by a CSS theme, or their own custom css, to change the appearance of an admonition.
  • Icon
    This is self explanatory. Sometimes you just need or want a different icon.
