Define spins at reference frequency for IMRPhenomP

- This patch uses f_ref instead of f_min in XLALSimIMRPhenomPCalculateModelParameters()
  to compute the IMRPhenomP model internal physical parameters from the LAL frame.
- The main PhenomP function XLALSimIMRPhenomP() also needs to take f_ref to compute
  integration constants for the alpha and epsilon angles. This is done so that for
  aligned-spin a change in f_ref should not change the phase of the waveform.
- Check whether f_ref is positive in the PhenomP functions. If f_ref = 0 is passed to
  ChooseFDWaveform then we set f_ref = f_min there.
- Change comment for phic parameter to be
  /**< Orbital phase at the peak of the underlying non precessing model (rad) */
pulsarpputils: changes variable min to mins, so as not to class with python min function
crab_ephemeris.txt: updated ephemeris to include values from 15 Aug 2012 (56154 MJD) to 15 April 2014 (56762 MJD)
Window.c:  edit a comment

- explain one limiting case for the Kaiser window
TimeSeriesInterp.c:  adjust the interpolating kernel's bounds

- make them time-symmetric
TimeSeriesInterp.c:  tie the no-op threshold to kernel length
TimeSeriesInterp.c:  add Kaiser window envelope to kernel
Adding scripts to ../TwoSpects/scripts/ScoX1/. Grant David Meadors, 2014-06-09 (JD 2456818)
calcSigmaH0.r provided the quadrature error calculations and formatted answers into a form for the Scorpius X-1 MDC submission table,
createAllPulsarGraphs.r ran createOutputSummary.py over multiple pulsars in the MDC and did parameter estimation and upper limits,
createOutputSummary.py concatenated text output and generated parameter space heatmaps,
createScoX1dag.py made the Condor DAG files for the MDC and related tests,
hEffDist.r simulated a range of cos iota and h0 values to estimate the h0-cosi ambiguity,
Running these files with some input arguments will require MDCv6_freqband.dat, MDCv6_master.dat, and/or MDCv6_open_table.dat,
which are available on the Scorpius X-1 Mock Data Challenge wiki."
