Fixed image extension pb in double weighting/single image mode.
Improved debug info for memory allocations in FFT and FITS libraries.
Fixed crashes with DETMODEL magnitudes on null measurement weight maps.

Improved MKL autoconfiguration.
Improved vectorization in FITS data transformations and FFT-based convolutions.

Fixed triggering of model surface brightness measurement.
Added new FLUX_DETMODEL,FLUXERR_DETMODEL, MAG_DETMODEL,MAGERR_DETMODEL, FLAGS_DE
TMODEL and CHI2_DETMODEL measurement parameters that apply on the measurement im
age a model fitted on the detection image (two PSF models required); these new p
arameters are meant for measuring faint galaxy colors.
