Bug: protoc-gen-go dev folder cannot be regenerated after error

[abjeni]

Whenever I modify the template files and create a compilation error in the generated zorums files in the dev folder, I encounter a problem when I try to fix it.
The dev make rule is used to regenerate the dev files, it depends on installgorums which depends on gen_files which contains template_static.go, which is created using protoc-gen-gorums. protoc-gen-gorums crashes and prevents the dev folder from being regenerated.
I have found the error is in gorums_bundle.go, because of os.Exit(1). This is intended behavior, but combined with the makefile dependencies it becomes a problem.

// loadPackage returns the parsed package.
func loadPackage(pkgPath string) *packages.Package {
	cfg := &packages.Config{
		Mode: packages.NeedName | packages.NeedFiles | packages.NeedSyntax | packages.NeedImports | packages.NeedTypes | packages.NeedTypesInfo,
	}
	pkgs, err := packages.Load(cfg, pkgPath)
	if err != nil {
		log.Fatalf("failed to load %s: %v", pkgPath, err)
	}
	if packages.PrintErrors(pkgs) > 0 {
		os.Exit(1)
	}
	// Since Load succeeded and pkgPath is a single package, the following is safe
	return pkgs[0]
}

In order to reproduce this bug you can modify or delete a file in the dev folder to contain a bug, and run make dev.

I get around this issue by commenting out the protoc-gen-go file in the makefile each time I introduce a compiler error in the dev folder.
I once forgot to uncomment it and it slipped into commit d09d76f.
