Support for showing if app is 32bit vs 64bit, and support for doing message hooks on both

Added support for message hook viewer to hook both 32 and 64 bit
applications.
Fixed filtering on the msg hook viewer
Added custom filtering on msg hook viewer
Added Process Id targetting on msg hook viewer
Added SetMsgHook.exe command line app as an alternative way of starting
msg hook viewer.
