Changelog:
* Thankfully, all of the problems triggered by Dial-a-fix were not actually Dial-a-fix's error; it was the new version of MSHTML.DLL that Microsoft released in an optional Windows Update package.
* Added a check for the MSHTML.DLL registration bug. Dial-a-fix will not register MSHTML.DLL if it is version 6.0.2900.2838, and will instead present a dialog explaining why.
* Box #5's "OLE" section and the "unregister before register" options will both return in v0.58, since they have been tested extensively and found to be safe.
