New update - bug fixes

Thanks to community feedback we're able to fix issues, and we hope to fix them quickly. Some fixes here include:

-adjusted enemy speed (hopefully to avoid spin outs)
-removed joint from drag/drop (no longer throw towers around, though no longer -drop them accidentally while they are swinging)
-fixed round begin / round end issues
-added close button to wave (in case we really didn't fix round begin/ round end issues)
-modified zoom out to allow for a larger view of the area
-fixed please wait dialog to be customizable so the user knows more of what's going on
-resized round control end so the wording fits without wrapping

You should get an automatic update soon.
