William Carroll 0244474e9f Debug startup, support LSP, update KBDs
Debug startup:
- some packages were missing explicit use-package calls, which made this
  configuration incompatible with fresh computers. After crashing my MBP
  and trying to get this working thereafter, I learned.

Support LSP:
- LSP support for Haskell is good; embrace and prefer over Intero

Update KBDs:
- preferences change
- changing to a light theme (for now)
