[PATCH v2 0/1] MR2377: sppc: Add stubs for MS Office.

[Daniel Tang (＠danielzgtg)]

After this and the related MRs, MS Office 365 finally loads. We see the fancy start screen, and we need modify the options to trust the folder we have our Word documents in. This works for `WINWORD.EXE`, `EXCEL.EXE` and `POWERPNT.exe`. I am able to open an existing file and view it.

This MR is limited to showing the first page or so of the Word document. It freezes with the Wine crash dialog basically the moment right after the screen is rendered. There is no backtrace in the dialog, but winedbg points to `v8jsi.dll` and so does the console output without winedbg. Creating new documents is not achieved by this MR either.
