Fix x64/Debug build on MSVS

Also add a CONTRIBUTING.md, that GitHub will link to in the pull request
creation page.

glog: release 0.3.4

migrate to https://github.com/google/glog
use autoconf 2.69 / automake 1.14.1

- ssize_t
Since Windows does not have ssize_t, we need to include BaseTsd.h and
use SSIZE_t instead.

- include algorithm
MSVS 2013 requests developers to include algorithm when they use
std::min.
