Nastran - reading free format

Cross-ref : EP#2494

Reading of free format Nastran file (e.g. with surfaceFormatConvert) seems to be an issue - the Z coordinate is wrongly interpreted/truncated.

For testing, pushed as fix3189-nastran-reading based off of 2312. If tests OK, can then proceed to add to other maintenance branches.

Tested fix3189-nastran-reading - worked with both .nas and .nastran

Note that the 'nas' format actually bypasses the regular writer (ie, no fields!) and only writes geometry and only in free format.

Note: the PLOAD4 output for the surface writer looks a bit suspicious. According to the online docs it specifies the loads on the corners of the face. Not sure why we are writing the components.
