Two Dozen New Functions!

Inspired by the utility library underscore.js, we've added a bunch of new utility functions to Sprig. Many of these are designed to work on dict and list types (and for the time being, on tuple as well).

Highlights:

• semver and semverCompare were added by popular demand.
• list replaces tuple
• join was fixed
• Added:
  • first
  • last
  • intial
  • rest
  • prepend
  • append
  • toString
  • toStrings
  • sortAlpha
  • reverse
  • coalesce
  • pluck
  • pick
  • compact
  • keys
  • omit
  • uniq
  • has
  • without
