chore(developer,windows): consider eliminating use of bin/ folders

Windows and Developer builds currently copy built files from e.g. /developer/src/tike/bin/Win32/Release/tike.exe into /developer/bin/tike.exe (similar patterns for other projects in Windows and Developer).

The problem is that this means there are two copies of each built file, and it's not clear which is authoritative. Also, if there are debug and release builds, they both copy into the same place, which can lead to confusion.

It might be best to have only the one copy, in /developer/src/tike/Win32/Release/tike.exe, or else to consider updating project configurations to emit binaries to /developer/bin/tike.exe?

Not going to rush into this change because it leads to a lot of busywork!
