Janet 1.28.0

Overview

• Various bug fixes
• Make nested short-fn's behave a bit more predictably (it is still not recommended to nest short-fns).
• Add os/strftime for date formatting.
• Fix ev/select on threaded channels sometimes live-locking.
• Support the NO_COLOR environment variable to turn off VT100 color codes in repl (and in scripts).
  See http://no-color.org/
• Disallow using (splice x) in contexts where it doesn't make sense rather than silently coercing to x.
  Instead, raise a compiler error.
• Change the names of :user8 and :user9 sigals to :interrupt and :await
• Change the names of :user8 and :user9 fiber statuses to :interrupted and :suspended.
• Add ev/all-tasks to see all currently suspended fibers.
• Add keep-syntax and keep-syntax! functions to make writing macros easier.
