I've uploaded it here:
http://www.sendspace.com/file/g3614u. I will say though, that it's certainly not going to be the easiest thing to improve upon. The little dependent even guy that follows you around has some info (targeted at someone else a long time ago), but I noticed that some of it wasn't revised, so there's a couple things that don't make sense. You can just ignore him really.
Anyways, you will probably have a lot more luck with the system I started in HMTK (it's in my signature). There's the bare minimum of a furniture system (only one item can be placed) in it, which can be accessed when interacting with the diary by the bed (like in most Harvest Moon games). What it does is really cool: it actually uses tiles from the tileset, and then literally changes the map data with the tile id for that tile. The farming system also uses this technique, on a far larger scale. Just check the code for any of the tools. The classes that handle the functionality for the tools have confusing names like Axe, Hammer, Hoe, etc ;)
There's one thing to note about the system in HMTK though: it uses the default tilemap built-in to RMXP. Essentials has some tilemap re-writes, where some of the naming conventions are changed. You should be able to play with the naming of the code I already have there for the tilemap related stuff and get it working if you're good and looking through code. That was on my to-do list for HMTK to make it Essentials compatible by request, but I never got to it. Hopefully that points you in the right direction. If not, I can probably whip up another novel to post in your visitor messages.
