Fixed some more bugs parsing 3-winding transformers. Still not working for WECC
problems.
Made some fixes to PTI/v33 parser and committing new GOSS parser. GOSS parser
still needs additional debugging.
Fixed up additional problems with GOSS parser. Seems to be working now but GOSS
data sets still have problems.
Switched input deck back to the usual default network configuration file.
Modified build so that powerflow and powerflow2 are in separate directories to
minimize build time if only building one of the applications. Also turned of the
powerflow component test to speed builds.
