CRAN release 0.4.20

1. Remove check for Yahoo Finance cookies because the site no longer responds with a cookie, and that caused the connection attempt to fail. This affected getSymbols(), getDividends(), and getSplits(). Thanks to several users for reporting, and especially to @pverspeelt and @alihru for investigating potential fixes! #358

2. Update getSymbols.yahooj() for changes to the web page. #312

3. Add HL() and supporting functions. These are analogues to HLC(), OHLC(), etc.Thanks for Karl Gauvin for the nudge to implement them.

4. Add adjusted close to getSymbols.tiingo() output. Thanks to Ethan Smith for the suggestion and patch! #289, #345

5. Use a Date index for getSymbols.tiingo() daily data. Thanks to Ethan Smith for the report! #350

6. Remove unneeded arguments to the getSymbols.tiingo() implementation. Thanks to Ethan Smith for the suggestion and patch! #343, #343

7. Load dividends and splits data into the correct environment when the user provides a value for the env argument. The previous behavior always loaded the data into the environment the function was called from. Thanks to Stewart Wright for the report and patch! #33

8. Make getOptionChain() return all the fields that Yahoo Finance provides. Thanks to Adam Childers (@rhizomatican) for the patch! #318, #336

9. Add orats as a source for getOptionChain(). Thanks to Steve Bronder (@SteveBronder) for the suggestion and implementation! #325

10. Improve the error message when getSymbols() cannot import data for a symbol because the symbol is not valid or does not have historical data. Thanks to Peter Carl for the report. #333

11. Fix the getMetals() example in the documentation. The example section previously had an example of getFX(). Thanks to Gerhard Nachtmann (@nachti) for the report and patch! #330

12. Fix getQuote() so it returns data when the ticker symbol contains an "&". Thanks to @pankaj3009 for the report! #324

13. Fix addMACD() when col is specified. Thanks to @nvalueanalytics for the report! #321
