added functions getRecordingNumber and getExperimentNumber to CoreServcies. Extended NetworkEvents plugin to send this upon request

Fixed: Changing data directory in GUI did not take effect if a recording had been started (and stopped) before. Only the first directory before the first recording was used. Fixed: EventBroadcaster was linking to Debug version of open-ephys.lib in Release mode

added functions to network module to retrieve acquisition/recording status and the current recording path

SpikeDetector: set electrode ID on spike events

SpikeDetector now sets electrodeID on spike events.  SpikeDetectorEditor now correctly initializes the selected electrode.

Implemented record control via network events (new version using CoreServices namespace)
