Good practices and syntax sugar for Golang

I see no snake cases in the project, only 2 times when i used SF_something instead of SalesforceSomething or salesforceSomething.

I'm working on setting up a travis file so you can do automatic CI with linting. By running the linter manually, I get the following. It's not really an issue, but a nice addition to the project. 😃

src/GoS2S3/App.go:39:6: don't use underscores in Go names; var SF_Soap should be SFSoap
src/GoS2S3/App.go:40:6: don't use underscores in Go names; var SF_BasicAuth should be SFBasicAuth
...
src/GoS2S3/ConfLoader.go:49:2: don't use underscores in Go names; struct field Instance_url should be InstanceURL
src/GoS2S3/ConfLoader.go:51:2: don't use underscores in Go names; struct field Access_key_ID should be AccessKeyID
src/GoS2S3/ConfLoader.go:52:2: don't use underscores in Go names; struct field Secret_access_key should be SecretAccessKey
src/GoS2S3/ConfLoader.go:53:2: don't use underscores in Go names; struct field Session_token should be SessionToken
src/GoS2S3/ConfLoader.go:56:2: don't use underscores in Go names; struct field S3_destination_bucket should be S3DestinationBucket
src/GoS2S3/ConfLoader.go:57:2: don't use underscores in Go names; struct field S3_destination_path should be S3DestinationPath

I did to maintain the name of the variable similar as the json variable name (for immediate find when searching in the project). Obviously if there are better reason for changing those variables i can refactor the code :)
