Removed premature IMAP optmization, causing attachments corruption.

This patch would "corrupt" some attachment when viewing them, or
saving them to the local filesystem. Files would be truncated, or
exceed in bytes, rendering them useless.

Multiple fixes to logging subsystem

  * Defaults.plist: don't hardcode the loglevel for
    WOHttpTransactionLoggerConfig, use default

  * Templates/WOxElemBuilder.m: don't setLogLevel on the defaultLogger
  * WOApplication.m: don't setLogLevel on the defaultLogger
  * WOHttpAdaptor/WORequestParser.m: don't setLogLevel on the defaultLogger

  * NSObject+Logs.m (debugWithFormat:arguments:): check current
    logLevel value before calling [NGLogger logLevel:message:]
    This squelches debug message at lower log levels
  * NGLogger.m (_logLevelForString): fix the check and return
    the defaultLogLevel instead of hardcoding INFO
