ProjectFileParser can be extracted in a user defined dir

Proposition for Issue #28

[gluck]

I'd rather avoid making this configurable, it shouldn't be (many gradle plugins download&execute binaries, I've never seen on make the location configurable)

[tekuser]

Yes that makes sense!

Do you know where the std location is for gradle-downloaded-binaries ? I've mostly seen ppl use HOME/.gradle, but not sure it's a standard

[tekuser]

Gradle download dependencies in the user's HOME/.gradle/ (there is a cache inside).
So gradle-msbuild-plugin.jar is downloaded somewhere in HOME/.gradle. But the plugin extract the ProjectFileParser.exe in the user's temp dir (defined by the env var %TEMP% or %TMP%).

So we can do the same thing as in the gradle-nuget-plugin:

l28: File nugetExe = new File(temporaryDir, NUGET_EXE)
