For Mixed Platform use AnyCPU
For Mixed Platform use AnyCPU

This allows the assemblies to be used on 32-bit (x86) and 64-bit.
Two assemblies were left as x86: SIL.Media and SIL.Windows.Forms.Keyboard
SIL.Media because it has platform specific dependencies
and keyboard because a test fails when it isn't x86.
