+ Rewrite projectile integration.
+ Fix per-frame workspaces not cleaning up after itself when an
frame-associated workspace (or its frame) is destroyed.
+ Alias +workspace-p to perspective-p instead of persp-p (which isn't as
accurate, because it counts nil as a valid perspective).
+ Extract orphaned-buffer list functionality in +workspace-buffer-list
into seperate function: +workspace-orphaned-buffer-list.
+ Allow toggle-debug-on-error to catch workspace errors.
+ Remove +workspace/kill-session-and-quit (never used)
+ Ensure persp-mode is loaded as late as possible.
This is a breaking change! Update your :popup settings. Old ones will
throw errors!
Doom's new popup management system casts off its shackles (hur hur) and
replaces them with the monster that is `display-buffer-alist`, and
window parameters.
However, this is highly experimental! Expect edge cases. Particularly
with org-mode and magit (or anything that does its own window
management).
Relevant to #261, #263, #325
