ARROW-204: Add Travis CI builds that post conda artifacts for Linux and OS X

I tested this on my fork of Arrow, but ultimately we'll see if it works when the commit hits master. I've arranged so that packaging issues won't fail the build.

Author: Wes McKinney <wesm@apache.org>

Closes #79 from wesm/ARROW-204 and squashes the following commits:

afd0582 [Wes McKinney] Change encrypted token to apache/arrow, only upload on commits to master
58955e5 [Wes McKinney] Draft of automated conda builds for libarrow, pyarrow. Remove unneeded thrift-cpp build dependency
