Move .bashrc sourced files to ~/.bashrc.d/ .

Going to make things more modular and I can add files there that aren't
included in the repo.

.bashrc

 # shellcheck disable=SC2148 shell=bash
+# vim: ft=sh
+
 # If not running interactively, don't do anything
 [ -z "$PS1" ] && return
 
+# Source all of the files in ~/.bashrc.d
+for sourcefile in "$HOME"/.bashrc.d/*
+do
+    if [ -f "$sourcefile" ] && [ "$sourcefile" = "${sourcefile%.j2}" ]
+    then
+        # shellcheck disable=SC1090
+        . "$sourcefile"
+    fi
+done
+
