Disable "Prefer 32-bit" on executables

[ChlorideCull]

Some things make SaintCoinach.Cmd.exe try to use more than 4 GB of RAM, which fails as it's configured for AnyCPU and "Prefer 32-bit", which makes it run in 32-bit mode even on 64-bit machines.

It works as expected when clearing the flag manually using corflags /32BITPREF- .\SaintCoinach.Cmd.exe, so it should just be a matter of unchecking the "Prefer 32-bit" box in the properties on the projects.

As a bonus, the whole thing gets a bit quicker as the JIT can use 64-bit exclusive extensions.
