Version 1.0.0-b3

• Events can be accessed on a per-sample basis, through an overload of GetEvent with a sample parameter
• Parameters can be set to an empty string
• Put messages to the system log via Log(), Warn(), and Error().
• Fixed an exception when shutting down BCI2000
• Corrected timing of parameters loading, they now load after modules start (This is because loading parameters only loads their values. Adding parameters must be done with AddParameter before modules load)
