Add 32-bit support about softcam HOT 1 CLOSED

Done!

Decisions/Lessons learned are as follows:

• DLL names: Should be consistent. No need to add the suffix 32.
• dist directory layout: Separate directories for each platform (x64, Win32) are reasonable.
• Installing process: Needs to run once for each mode.
• Class ID/name: Should be consistent.
• Mixture use case: Possible. In our architecture, the DLLs at apps on each side communicate through shared memory, which can be accessible for both 32-bit and 64-bit DLLs at the same time.
• Calling conventions matter in 32-bit mode. Explicit declarations were needed at some points in the code.
