LibQurl v1.2.0

This update features a slew of enhancements and fixes primarily aimed at smoothing API interactions.

• Added DecodeJwt() to return an unobfuscated Map of the input JWT token.
• DecodeBase64() accepts a third parameter to mark the input as Base64URL, which will do a couple extra pre-transformations before decoding as Base64.
• Timestamp() now accepts a parameter to return multiple common internet standard formats.
  • Acceptable paramaters: Readable, SQL, ODBC, RFC 3339, Unix, asctime, RFC 1123, RFC 2822, FILETIME, EXIF, and RFC 850. See that method for output examples.
• SetPost() now returns the input's mimetype. This is useful for persnickety servers demanding an exact Content-Type to be reported in the headers.
  • Due to a behavioral quirk in libmagic, json data examined in memory is reported as text/plain. However, since passing an Object/Map/Array always results in a dumped json being staged, there is a specific override for that group which returns application/json.
• SetPost() now explicitly sets CUSTOMREQUEST to POST. This fixed a bug where POSTs would fail after GETs were sent after POSTs were sent.
  • ...yeah that was as dumb as you might imagine to track down.
• Fixed SetPost() unintentionally assigning POST data to the default handle
• ClearPost() now also zeros libcurl's UPLOAD flag.
• ClearPost() now explicitly sets CUSTOMREQUEST to GET for more intuitive behavior in mixed-request usage.
