Cleanup

[PuercoPop]

Tracking Issues:

• Remove terminfo from the repository (Remove terminfo from the repo #6)
• Remove trailing lines and tabs (Non-code changes #4) (Closes #4 #5)
• Reader hook patch
• Migrate to CFFI
• Remove Madeira port in favor of ASDF feature expressions (Replace madeira-port with ASDF feature expressions #7)
• Remove terminal glue
• Remove anaphoric variants in favor of alexandrias when-let if-let
• Scour through tokenrove's PR for unmerged changes from CVS

It may be a good idea to reorganize the code into directories for related functionality and split stuff like completion and paren navigation into its own system
