Cleanup whitespace in bootstrap tokenizer
Port my changes over to bootstrap, everything else left in caution
Inline identifiers bound to regexes, all of which are used but once
Align some things in the tokenizer for easier reading
Further condense for line width
Getting Bootstrap up to date again
Added a "just-lex" script
`SEMI` like before, ws_after = "(?:\\s+)", op use ws_after and parenIsForExpr
Adding space around caret
Convert strings to regexes in loop to avoid boilerplate
Updating Bootstrap tokenizer again, and Bootstrap grammer for the first time
