added methods to thingview to generate select buttons on the left-hand-side of the page. I'm still testing those.  also added some semicolond I forgot in controller.js, added a parseint to the Plant prototype so the height will always be an int, even if user gives a string.  also added a buildStarterThings method to make some things and add them to the model on startup.  this'll make testing the view methods easier
got thingView makeGrid and addGridSquare functions workinggit add .  hurrah!  Now to make the click event function right with the different types of buttons, and to generate a new button when a new Thing is created
selector buttons are now linked to objects in thingModel.allThings, and will show status of linked object when clicked.  had to shift a few event handlers around, and also reshuffled the thingController section of the code to make it easier to add handlers in multiple places, and to eventually turn the controller into its own object.  must now make newly-created objects append to the select list, and fix the weird bug i have where all the buttons stay pink forever
I totally forgot to give it a title up until now.  I feel like a newbie.  whoops
fixed forever-pink selector button problem.  in the makeButtonActive handler I'd replaced  with . fixed now
new Things are now being appended to the select list.  you can pick it and it will show its status like all the others.  yay progress.
