Localization review/cleanup

[jng]

Review the Maestro codebase for localization related issues:

• Mark lines containing unlocalizable string literals with NOXLATE
• Move localizable string literals into their respective resx file
• Where possible, externalize frequently used string literals into a string constant of a StringConstants utility class.
• Move strings in Resources.resx into a separate Strings.resx resource, to make such items easier to distinguish during the localization process
