New function WrtPSRFITSPar:

This will take the ephemeris table contained in files written in the PSRFITS definition, read it, and output it to an ascii par file.  This supports both the PSRPARAM and PSREPHEM tables found in varying versions of PSRFITS.

-- RDF, 16 July 2013
Updated include files to support changes to functions to be described elsewhere.

-- RDF, 2013 July 16
Changed call to ReadHdr(), to accomodate new argument.

-- RDF, 2013 July 16
No changes, just re-wrote after doing some debugging and removing print statements

-- RDF, 2013 July 16
Small bug fixes, allowed for larger numbers in output ascii profile files.

In ReadHdr.c:

- added ability to read par file table in PSRFITS (Using WrtPSRFITSPar)
  * both PSRPARAM and PSREPHEM tables can be read
- make polycos based on above par file, read them into memory -- useful for realigning profiles with new ephemeris.  Special case for DFB where we create multi-channel polycos to mimic tempo2-style polynomial information
- Moved reading of PSRFITS' POLYCO table (when read a version of PSRFITS in which it exists) to here rather than ReadPSRFITSData function
- Now accepts RunVars structure as argument to ReadPSRFITSHdr()

Main program.  Adjusted certain calls to support changes to routines used by AFR.

-- RDF, 2013 July 16
Added new objects to object lists for compiling AFR and AFR functions.
