Added simple support for dunst files. Since files can, similar to alacritty, not be included in dunstrc, the processor invokes a similarly invasive replacement method to add the base16 at the end of the config file. The procedure is similar to alacritty processor, the danger is also the same -- it works directly on the config file and will worst case delete the complete contents of this file. Since the processor is not tested (other than manually looking that it does what it's supposed to) the case of this happening is not negligible.

# Alacritty does not support including other files into

# change the user's configuration file *itself*.

#
|

# This will generally not be a problem, though it can lead

# '# Base16 [theme name] - alacritty color config'
|
|
# from which it will delete everything until it finds a line:
|
|
# '# Base16End [theme name] - alacritty color config'
|
|
# So, if you don't want to lose anything -
|
|
# Do NOT put anything important between those two lines.
