Add Python 3.6.7 to win-64

[tadeu]

From this build it seems that python-3.6.7-he025d50_1001.tar.bz2 was correctly constructed but there was a problem with anaconda upload (called by upload-package):

upload_package .\ .\recipe .ci_support\%CONFIG%.yaml
No numpy version specified in conda_build_config.yaml.  Falling back to default numpy value of 1.11
Adding in variants from internal_defaults
Adding in variants from .ci_support\win_c_compilervs2015cxx_compilervs2015vc14.yaml

Unfortunately the two rebuilds (1.0.481 and 1.0.482) triggered in #229 didn't work with the same problem :/

We are going to need more help from @conda-forge/core. Could it be a problem with the token?

Think PR ( #244 ) should fix this.

AppVeyor build for 3.6 now passes and the Python 3.6.7 build for Windows is now deployed. :)
