Build Errors when assemblyname starts with a number

[sbloomztf]

for example...

<AssemblyName>012Numbers And Spaces</AssemblyName>

Results in....

'global::WinRT' is a namespace but is used like a type
'WinRTExposedTypeAttribute' does not contain a constructor that takes 3 arguments
The name 'umbers_And_SpacesVtableClasses' does not exist in the current context

Looks like we will need to escape with a _ prefix when it starts with a number.
