Move "Build Options" to the build menu

[Al.B]

Currently, this option is in the Options menu, but I think that it makes more sense under build (next to target settings).  I understand the reasoning for this may be that the build options are an environment setting rather than a project-specific one, but I always look under build for this option.  It also doesn't really fit with all of the other items in the build menu, which are all environment related.
