Merge branch 'master' of github.com:nficano/python-lambda

* 'master' of github.com:nficano/python-lambda:
  Should address issue nficano#38.  The calls to determine whether or not a function exists wasn't calling multiple times if you have more than 50 lambda functions configured.  For those users who have lots of functions defined, the deploy will try to re-create an existing lambda function
  Found some holes in error handling when the config.yaml properties aren't set for the build, build/source_directories properties.  We now handle these cases correctly and default to the existing behavior if the values are missing.
  Related to issue nficano#64 "Subdirectories not included in zip package".
  Revert "Related to issue nficano#64 "Subdirectories not included in zip package"."
