Sawmill

NOTE: This is a BETA build!

This adds a sawmill building which is a more efficient replacement for the woodcutter yard. It allows up to three woodcutters, and woodcutters will produce twice as fast when working from here*. It is meant to be a tier 2 type building that is not easily built until you have your basic town infrastructure up.

Currently it requires the following to build:
100 Logs
65 Stone
20 Steel Tool**

Here are some preview shots:

Hope you enjoy!

* Work speed increase is based on time to take logs out of the building's storage, and convert to firewood. It does not account for time villagers take to go home, go to the stockpile, etc.

** There is a bug where the recipe shown on the toolbar tooltip does not include the image for steel tools (you will only see "x20" with no image next to it). At this time, I am unsure if it is something I can fix.
