Title: Support an optional environment variable to find FreeTDS.

Hey there,

I don't know if this small tweak is useful to you, but it is something I had to do to get this gem to install on Heroku successfully.

It made sense to have extconfig check if a FREETDS_DIR was set in the environment, and use its value if set, instead of just going with libdir and includedir config always.

Thanks!
