Added custom Projectile config, revised elisp and Org Capture

Added some blacklisted directories to Projectile

Wrote a function to make my code clearer with `add-to-list'

Updated Org Capture shortcuts, in particular the text displayed in the
user interface while entering the shortcuts.

+   Projectile is an awesome utility  which helps managing projects within Emacs.
+   It  will automatically  detect version  controlled directories,  and will  by
+   default assume this is a project I can be working on. However, there are some
+   directories that are version controlled that I  do not want to see in my list
+   of projects,  namely all the cached  AUR packages from my  AUR helper, ~yay~.
+   They are  all stored in  the same parent directory,  so let’s ignore  that. I
+   will  also  make  Emacs  ignore   all ~node_modules~  directories  it  could
+   encounter. And  for some reason, =~/.config/emacs= is always in  my projects
