Quantmod Versions Save

Changes

1. Add an environment variable to control whether to run tests that import from Yahoo Finance. getDividends() tests were failing because Yahoo Finance wasn't returning all dividend history for "CF".
2. Write one message the first time quantmod::as.zoo.data.frame() is called. This method was added years before zoo::as.zoo.data.frame() existed, but it should be deprecated in favor of the zoo version. The package that owns the class should also own the methods.

BUG FIXES

2. Fix getQuote.yahoo() for quotes in multiple timezones. Thanks to Philippe Verspeelt for the report and PR. #246 #248
