Windowed mode and some fixes

New small patch:

• Desktop client can now be played in WINDOWED mode! Crazy stuff I know. Despite GameMaker giving me bizarre issues that were breaking the game if you were resizing/dragging the window around, it seems like it's now functioning properly. Hopefully. Please do report if you find any issues with it.
• Partially fixed the weird browser issue where after prestiging the fullscreen game window would shrink, distort pixels and create black bars. This should be mostly fixed, but some browsers can still sometimes screw up the aspect ratio, so if that happens you can fix it by refreshing the page.
• Artifact-collected panel now shifts to the left side of the screen if the artifact-1o3-choice panel is also open at the same time. Not the prettiest solution but will do for now.

And as always, thanks for playing and all the feedback!
