gstlal-calibration/tests/check_calibration:  Improvements to pcal2darm_timeseries.py and plot_transfer_function.py

gstlal-calibration/tests/check_calibration/pcal2darm_timeseries.py:  Plot all timeseries on one figure. Improved formatting

gstlal-calibration/tests:  pcal2darm_timeseries.py:  Can now read from multiple calibrated frame cache files to compare different calibrations.

gstlal-calibration:  config files for comparing results for correcting for only kappas, f_cc, and all TDCF corrections.

gstlal-calibration:  Update gstlal-calibration.spec.in and debian/gstlal-calibration.install to package everything we need.

gstlal-calibration/tests/check_calibration:  Added GPS start time to name of files in pcal-to-darm plotting script.

gstlal-calibration:  Added debugging element splitcounter for printing buffer timestamps and offsets to screen and file.

gstlal-calibration:  Example in tests/check_calibration/Makefile for using transfer function plotting script.

gstlal-calibration:  New plotting script in tests/check_calibration/plot_transfer_function.py to plot transfer functions.

lal_transferfunction:  added event() function back in to get best possible transfer functions at EOS.
