AMDirectorySynchronizer in an AMAction3 so it can be added to a workflow

uses a timer to wait for five seconds before emitting copyCompleted

-AMDirectorySynchronizer::errorMessagesChanged and
progressMessagesChanged to now emit a single QString rather than the
whole list
Modified:
- AMUserSettings::remoteDataFolder ~ stores value from ini file (if no
value in found in the ini file for this key, then it will be blank)
- Altered the AMDirectorySynchronizer and
AMDirectorySynchronizationAction to load remote and local directories
from the ini settings
- AMSettings window to show the remoteDataFolder
