Various bug fixes

#22 by adding a line in the theme css, found via googling.

#18 fixed for Washing and drying. Currently it reloads the DOM for all
of the machines when an unload or load occurs. I also added a refresh
page button to facilitate consistent data across clients.

#17 I think I got this one by linking the JS models in drying.html. If
not that, then it is included from fixing the refresh bug.
Merge pull request #24 from jjallen37/machine
