TimeSeriesInter:  switch to Lanczos window

- now that the Lanczos window has been fixed, it works much better ;-)
tools package:  add unit test framework for TimeSeriesInterp.c
Add LALInference PP analysis DAG generator script to lalsuite, for lalinference review
Add option in ini file for web output path
Fix build error
SWIG: fix bugs in SWIG binary checking

- Fail if -version fails in _LALSUITE_CHECK_SWIG_VERSION()
- Use AC_PATH_PROGS_FEATURE_CHECK() to correctly find binaries
- Fail if no binaries are found
Tweak paths in lalinference pp pipeline
LALInferenceProposal: Add ensemble Stretch move (fix #1081)
Affine Walk jump working
LALInferenceNest: Remove PolarizationPhaseJump in favour of
CorrPolarizationPhaseJump
Fix paths in lalinference_pp_pipe
lalsimulation: generalize XLALSimDetectorStrainREAL8TimeSeries()

- use time-dependent geometric delay.  generalizes the function to long
  waveforms, and also naturally incorporates Doppler shift.
Add PP check scripts to example pipeline
lalapps_compareFstats: removed obsolete '--clusterFiles' option

- 'clusterFiles' were only written by obsolete CFSv1 code
pulsar/FDS_isolated: moved obsolete and unused test scripts into attic

- refs #20
lalapps_compareFstats: use vector-comparison function instead of bin-wise comparison

- more robust F-stat vector comparison, new input arguments specifying
  tolerances on L1-, L2- vector comparisons, relative angle, and
  relative error at respective maxima
- passes 'make check'
ComputeFstatTest: shortened Tspan, added SFT gap, added binary orbit

- used 'Sco-X1 like' asini~1.4, and Period~19h
- tests 2 skypositions, f1dot points, and orbital periods
- adjusted tolerances
- refs #535
TimeSeriesInterp:  performance improvement

- remove an auxiliary variable from the inner loop
lalinference: removed remaining references to currentParams in init
TimeSeriesInterp:  expand the documentation
