bug in bindatafs on windows

[sugacube]

There appears to be a bug when using bindatafs on windows OS.
This is manifested for example when trying to use qor/admin with bindatafs on windows, then some templates are not loaded resulting in distorted views.

See qor/admin#153 for how to reproduce.

Solution is to fix templates of bindatafs: update "Glob" and "Asset" functions: use "path" in stead of "filepath", and change \ to /. (although maybe better to us os.PathSeparator)

-- bindatafs.go.template:

func (assetFS *bindataFS) Glob(pattern string) (matches []string, err error) {
	pattern = strings.Replace(pattern, "\\", "/", -1)
	if len(_bindata) > 0 {
		for key, _ := range _bindata {
			if ok, err := path.Match(pattern, key); ok && err == nil {
				matches = append(matches, key)
			}
		}
		return matches, nil
	}

	return assetFS.AssetFileSystem.Glob(pattern)
}



func (assetFS *nameSpacedBindataFS) Asset(name string) ([]byte, error) {
	name = strings.TrimPrefix(name, "/")
	if len(_bindata) > 0 {
		return Asset(path.Join(assetFS.nameSpace, name))
	}
	return assetFS.AssetFileSystem.Asset(name)
}

func (assetFS *nameSpacedBindataFS) Glob(pattern string) (matches []string, err error) {
	pattern = strings.Replace(pattern, "\\", "/", -1)
	if len(_bindata) > 0 {
		nameSpacedPattern := path.Join(assetFS.nameSpace, pattern)
		for key := range _bindata {
			if ok, err := path.Match(nameSpacedPattern, key); ok && err == nil {
				matches = append(matches, strings.TrimPrefix(key, assetFS.nameSpace))
			}
		}
		return matches, nil
	}

	return assetFS.AssetFileSystem.Glob(pattern)
}
