Updated rules of 'VisualStudio.gitignore' about ATL Project.

　I added three new rules to **VisualStudio.gitignore** for Visual Studio **ATL Project**.

* [Dd]ebugPS/
* [Rr]eleasePS/
* dlldata.c

　**DebugPS** and **ReleasePS** rules are needed when you create an ATL Project and debug it with the web browser. **dlldata.c** rule is needed when you just work on ATL Project. Those two directories and the C file are automatically generated/updated everytime you build the project. You might don't want to add those to your commit.
　I know ActiveX is old creepy technology, but someone still gets benefit from it. :)
