2.13.0: support HHVM 4.29+

Removes all support for &$references, which were removed from the Hack language in HHVM 4.29.

2.12.6: support fbexpect 2.6.1+

v2.12.6

support fbexpect 2.6.1+

2.12.5: bugfix release

v2.12.5

fix issue revealed by HHAST update

2.12.4: fix for function typehints with variadic argument

v2.12.4

support lambda typehints with a variadic argument (#26)

2.12.3: improve ScannedTypehint::getTypeText() formatting

improve getTypeText() formatting (#25)

Previously we'd just dump the "AST without trivia", so there are no spaces between anything.

This adds spaces where people (and hackfmt) normally put them.

2.12.2: namespace fixes & cleanups

add fancy arguments to getTypeText() (#24)

This replicates the functionality from hh-apidoc, but actually does it correctly.

I'm moving that logic here because otherwise it would be much harder/more confusing to correctly apply the rules at all levels of recursion.
