[HIDPARSER]

Browse source 
- Rewrite hidparser so that it support multiple top level collections
- Add support for flat collection context meaning all context structures are aligned in after each other. The reason this is required is that usermode hid.dll will access the same structure and thus can't use kernel pointers. User mode hid.dll is used to support keyboard with custom keys (for example search key, email key etc)
