Improved script builtin function parser

- Removed duplicate code shared between script_hp_add and
  script_parse_builtin.
- Improved error handling in script_hp_add to be on par with the
  script_parse_builtin version.
- Added script->add_builtin function, providing a hooking point for
  plugins (i.e. text editor syntax definition generators) to obtain the
  builtin commands list.
- Special thanks to Ind.
