Updated function definition of getModelPatch to match its
calling in tractor/engine.py .
Added preliminary support for the KIDS survey.
Added a command-line parameter to specify the survey.
Added KIDSWCS, KIDS_photocal and KIDS_epoch, corresponding to there
PS1 counterparts.
Improved the support for multiple surveys, in particular KIDS.

- Added --survey argument to LensTractor.py
- Created kids.py with the following functions:
  - KIDSWCS, KIDS_IQ, KIDS_photocal, KIDS_epoch
- Added kids.py to __init__.py
- Added survey support for photcal and epoch in dm.py
- Added KiDS support to dm.py

- Added KIDS_imshow_settings() to set KIDS specific plotting options.
- Added PS1_imshow_settings() to set PS1 specific plotting options.
- Added support for plotting settings based on survey.
- The KiDS 'chi' images have different units than the PS1
  'chi' images. It should be checked whether this causes problems
  with the modeling.
Added support for plot settings based on survey.
Merge branch 'kidssupport' into develop.
+ Added support to specify plot settings per survey.
+ The sace of the KiDS residual 'chi' images is not in units of sigma.
  It should be checked whether this causes problems with the modeling.
