TYPE: bug fix

KEYWORDS: WRFDA, IO_NETCDFPAR

SOURCE: Jamie Bresch (NCAR)

DESCRIPTION OF CHANGES:
Problem:
WRFDA does not build after commit e018624.

Solution:
Add io_netcdfpar to Registry.EM_COMMON.var

LIST OF MODIFIED FILES:
M       Registry/Registry.EM_COMMON.var

TESTS CONDUCTED:
1. WRFDA builds after the fix
2. Jenkins is all pass (for real).
