Naming a Plugin with a number as the first character causes errors

When naming a plugin, having a number as the first character causes a toast to pop up that says: "Failed to generate project files"
However, the plugin is available to look at and edit in Editor, and files will be generated that can be viewed in windows explorer, but the plugin and its associated files will not be added to the Visual Studio project.

1. Open any C++ project in Editor.
2. Navigate to Edit->Plugins
3. Click on 'New plugin'
4. Select 'Blank' , name the plugin "7HOG" , click 'Create plugin'

Results: Toast comes up that says: "Failed to generate project files". Plugin shows up in plugin list, files are generated in the correct project path, Plugin is NOT added to the Visual Studio project.

Expected results: Don't allow the user to put a number as the first character of the plugin name.
