moves authentication to httr-0.3 tokens. in development (#72)
Unclear how token caching works at this time.  Currently code still uses the environment variable to cache, and makes a repeated call to fs_auth if the token is not available.  Perhaps repeating the call is how we are supposed to load stored tokens?
use jsonlite instead of RJSONIO
a few more configs fixed
Revert to RJSONIO, fixes #73.
Also minor formatting improvements and updated test.  Should be passing unit tests now
bump version and update NEWS
tells travis to use github version of httr
try making call to fs_auth explicit in test
cache credentials for non-interactive testing #74
cache credentials for non-interactive testing #74
add jsonlite to SUGGESTS just to make httr happy
try a different way to install httr from github?
use RJSONIO to parse
whoops, wrong value for request
avoid warning
remove fs_embed and XML import, since function not working
use RJSONIO for all parsing, avoid jsonlite dependency
whoa, did not notice some tests required extra libraries gdata and ggplot2. added to suggests now
