Great debugger helper bug fixing spree.

- Fix extractTemplate() not to kill blanks in case there is no
  blank after a comma, fix hardcoded types accordingly.
- Make niceType()'s regexps ignore blanks after commas, add
  unsigned short as char_type and cache the mappings, making
  them work for CDB.
- CDB: Parse map output of dumpers correctly, generally don't
  confuse the parser by unknown keywords encountered when
  parsing children, thus enabling simple QMap types.
- Make dumpInnerValueHelper output std::string types.
