A while back I changed code such that Lookup.LookupType is written as a
comment in XML, and ignored when compiling. The LookupType from type
of actual subtables in a lookup were used during compilation instead.
This caused the problem where an empty lookup (one with no subtables)
would lose its lookup types, among other subtle problems.
With this change we revert above behavior, but keep the benefits: if
Lookup.LookupType is different from actual lookup type of the subtables,
compilation raises an exception. Setting LookupType on Lookup object
or in XML is optional now, but written out by default in XML (instead
of as a comment).
This changes XML output for all GSUB/GPOS tables. I'm sorry for the
noise. Please update your sources.

This does it for the simple cases, but not propagated ones.
Also, when writing to XML, if a Count or otherwise-computed value is
not set, don't write it out.
gid=0 means "not mapped". Many of the cmap formats use this to
optimize byte encoding. When reading these tables, we don't
want to map charcodes to gid0 in the resulting struct.
Tests pass on both Python 2 and 3 now. Yay!
MockFont is handy for mtiLib.__init__:main(). Not sure how useful it is
otherwise, and what to replace it with.
I'll first make Python 2 and 3 both generate same output for tests with
MockFont, then will probably hardcode glyphorder and remove MockFont
completely and remove hacks I added to make tests work with MockFont.
This makes sure we upload the same files to Github Releases and PyPI.
Currently we were building them twice, with the risk of different files
being uploaded to the two repositories.
We no longer run tests on python3.4 on Windows; 2.7 and 3.5 are enough for Windows I believe.
We do test python3.4 on Linux (not for long, I hope).
We shall add 3.6 when Appveyor provides that by default.
This should speed it up a bit, as brew will download a pre-compiled "bottle", whereas pyenv compiles python from source.
The current 'python3' formula on homebrew is 3.6.0, so let's use that.
