+ The "main" workspace is no longer treated especially, and can be
renamed or deleted. Fixes issue mentioned in #200.
+ In the disastrous event that there are no workspaces left, a main one
is generated and switched to. Under no circumstances should the use be
left in the nil perspective!
+ Fix the :tabr[ename] ex command throwing argument errors.
+ Refactored most workspace functions.
+ New command: +workspace/close-workspace-or-frame, which is bound to
C-S-w in my private module.
+ enable lexical-scope everywhere (lexical-binding = t): ~5-10% faster
startup; ~5-20% general boost
+ reduce consing, function calls & garbage collection by preferring
cl-loop & dolist over lambda closures (for mapc[ar], add-hook, and
various cl-lib filter/map/reduce functions) -- where possible
+ prefer functions with dedicated opcodes, like assq (see byte-defop's
in bytecomp.el for more)
+ prefer pcase & cond (faster) over cl-case
+ general refactor for code readability
+ ensure naming & style conventions are adhered to
+ appease byte-compiler by marking unused variables with underscore
+ defer minor mode activation to after-init, emacs-startup or
window-setup hooks; a customization opportunity for users + ensures
custom functionality won't interfere with startup.
