genGUIDs

Adds new tool window to Tools menu that generates guids like Create GUID built-in external tool but in more handy way. Supported formats:

• ToString() (xxxxxxx-xxxx ... xxxx)
• [Guid("xxxxxxx-xxxx ... xxxx")]
• <Guid("xxxxxxx-xxxx ... xxxx")>
• IMPLEMENT_OLECREATE(...)
• DEFINE_GUID(...)
• static const struct GUID = { ... }
• Registry Format (ie. {xxxxxxx-xxxx ... xxxx})

Can Undo guid generation and allows to change guid case - Upper or Lower Invariant.
