Prefer32Bit should be false

[andersforsgren]

The <Prefer32Bit> flag in FlaUIInspect.csproj is left at default (true) in release mode (and curiously set to true in Debug mode).

If the "standard scenario" is to inspect x64 applications when on 64bit Windows, the flag would be better set to false so FlaUIInspect starts as x64.

Since there are some known issues inspecting x64 apps with FlaUIInspect running as x86, and the Choclatey build is using AnyCPU+Prefer32Bit so it's running x86, users will often have to compile themselves to avoid that issue.

Happy to submit a PR for this if this sounds like a good change.
