pancake f2563a7509 * Export 'srwx' perms of sections in rabin2 -rS
- Handled by 'S' command
* Added dummy 'z' command to handle zignaturez
  - Added more dummy 'az' commands
  - RCore now depends on RSign
* Some refactoring and speedup in _update method of RSearch
  - Added support for distance search (maybe buggy and incomplete atm)
  - Fix binary mask for keywords after previous commit
* Added 'r_str_rwx*' helper functions in r_util
