update dependencies
DRY in test specs by adding trait WithConfig
misc - reformat code & remove unused imports
simplify object `Common`  by an incompatible config: com.imadethatcow.hipchat.secure is replaced by com.imadethatcow.hipchat.api-url
binary incompatible: We should not declare roomIdOrName, emoticonIdOrName as `Any`. Refactored to `String` type
use sbt-sonatype, sbt-sonatype sbt plugins
only re-format code using scalariform
DRY - add & use Common.resolveBoolRequest
fixed some issues with config loading, as well as errors due to new parameters in hipchat's responses
