appEnvironment is null in the Program ctor.

[TelWang]

When I run the CultureInfoGenerator directly , exception is thrown, appEnvironment is null.
maybe, the tool will be integrated into vs, but shall we give a default value when appEnvironment is null?
code change to :
_appName = appEnvironment != null ? "CultureInfoGenerator" : appEnvironment.ApplicationName;
_appPath = appEnvironment != null ? "" : appEnvironment.ApplicationBasePath;

another issue, in the Main method, the outputFilePath need changed from "../Microsoft.Framework.Globalization.CultureCache/CultureInfoList.cs" to
"../Microsoft.Framework.Globalization.CultureInfoCache/CultureInfoList.cs"

@TelWang the CultureInfoGenerator works fine if we change the outputFilePath as you mentioned above, I don't face an issues with appEnvironment

@DamianEdwards we need to change the outputFilePath to "../Microsoft.Framework.Globalization.CultureInfoCache/CultureInfoList.cs" because the old value causes a DirectoryNotFoundException
