Upgrade logging to be compatible with CocoaLumberjack 2.0.0-beta4

Upgrade CDT Logging macros to use the new updated logging macros
from CocoaLumberjack 2.0.0-beta4. This will mean that it will not work
with versions below 2.0.0-beta4.

Changed how attachments are downloaded, instead of using an dispatch_once
block, use a dispatch_sync instead, which means the blocks will be queued
and any subsquent downloads will not go ahead.
