Ported chilitags.js to use most of chilitags 2

chilitags.js now has
- setFilter and find from Chilitags
- set3DFilter, set2DFilter, estimate, readTagConfiguration, setDefaultTagSize,
  readCalibration, getCameraMatrix, and getDistortionCoeffs from Chilitags3D

set3DFilter and set2DFilter respectively correspond to Chilitags3D::setFilter
and Chilitags3D::getChiliags().setFilter

encode, decode, draw, Chilitags3D::getChiliags().find, and
Chilitags3D::estimate(map<int, Quad>) are left as an exercise to whoever needs
it first ;)

The samples are GUI's to the full interface, e.g. one can set the filtering
parameters from input boxes. They ended upd being rewritten a lot...
