Line 386 - Real Power and Reactive Power are more accurate names to distinguish MW and MVAR

Change the "Note" field for "Power Units" to "Enumeration of Power Units, e.g., MVA (total power), MW (real power), MVAR (reactive power)", changing the "Note field for "Energy Units" to "Enumeration of Energy Units, e.g., MVAh (total energy), MWh (real energy), MVARh (reactive energy)", and removing the "VAR Units" row from Table 6-7.
