Remove unused parts, updated my theme

== ALL FILES ==
The org TOCs were unused on export, and Spacemacs makes it useless.
This commits removes them. The startup header of org files is moved to
the header file.

== AWESOME ==
In the Awesome file, this commit removes everything about custom theme
creation as this part is not yet used. I also remade and reorganized
the windows titlebars.
Theme files for Awesome shall be added soon. The wallpaper functions
were updated accordingly.

In the autostart part, I updated some commands (picom will not launch
if another instance is already running, same for the XFCE polkit), and
I added PumoPM to the autolaunched software (power management). Due to
some issues, I also let Awesome one second before launching
`set-screens'.

== AWESOME AND CUSTOM SCRIPTS ==
This commit also removes any usage of pywal. My Awesome configuration
and my custom scripts were updated accordingly.

== CUSTOM SCRIPTS ==
In bin.org, the script `pape-restore' has been removed since it can
now be replaced with the command `nitrogen --restore'. `pape-update'
has also been updated so it doesn’t depend on `pape-restore' and gets
a random wallpaper for nitrogen to set without the help of pywal.

== XRESOURCES / ST AND PICOM ==
St’s transparency was tweaked to match my windows’ titlebar
transparency. It also got the Nord theme mentionned above. Some custom
Picom rule about St’s transparency has been removed.

== PICOM ==
I made it clearer in the index and on Picom’s page Picom is the new
Compton.

== FIREFOX ==
A new git submodule (blurredfox-nord) has been added, which adds some
transparency to Firefox as well as some Nord colors.

== I3 AND POLYBAR ==
My i3 and Polybar config have been deprecated since I do not use them
anymore.

== SPACEMACS ==
Changed shortcuts for config files
