SWIG3 workaround and new .gitignore

SWIG3 has some issues with %pybuffer_binary. A wrapper had already been
added since it does not handle void* pointer arguments correctly. This
renames the other argument since it also doesn't handle arguments named
"size" correctly.

This also adds a .gitignore file to reduce the likelihood of editor and
build artifacts getting accidentally swept up in git commits.
