Massive configuration overhaul

Currently paying the price of months of non-diligent git usage.

Here's what has changed.

- Theming support in Gvcci and wpgtk
- Dropping support for i3
- Supporting EXWM
- Many Elisp modules
- Collapsed redundant directories in ./configs

configs/shared/.gvcci/themes/lego_manhattan/tilix.json
