PS 3.1.6 Release

1. The same font (Droid Sans) is now used to draw the status line, the
message line and all glyphs, on all browsers.

2. Vertical centering of glyphs has been improved on some browsers.

3. A problem with fonts failing to load on some browsers has been fixed.
However, for the fix to take effect, you must use the version of
game.html included in the latest 3.1 Devkit, which can be downloaded
from the link above.
Merge branch 'master' of https://github.com/ProfBMoriarty/PS3.1

Conflicts:
	game.html
	game.js
Consolidate Perlenspiel file version numbers
Reorganize folders. Engine source (js, css, html, fonts, png, all directly relating to the engine as it is released) go into the src folder. This includes minified versions. Experimental game.html/js projects are in the experiments folder.
Include the workspace.xml file. I'm not sure if this should even be in git, though
Merge branch 'master' into md_sandbox

Conflicts:
	ps3.2.0.js (made copy in src folder named psMulti)
	src/game.html (removed extra PS._sys(), since it's now done in game.js)
