* Initial support for visual cursor with invert cons in 'pd' bytes
- Some changes in '*' and '/' keys in visual modes (+-16)
- '+/-' in visual cursor works as in r1 (inc/dec cursor byte)

- 'zf' stands now for function signatures (args, types, ret, ...)
* Merge r_trace into r_debug (RDebugTrace)
- Implement 'dt' command to manage debugging traces
- TODO: Track register values and memory changes
- Added dbg.trace and dbg.trace.tag
* Added r_sys_now() to retrieve ut64 value of current time
- Must check endianness issues
* Initial work trying to implement RPATH support to ELF
* Less flat command tree
- 'dt' is now 'dbt'
- 'dk' is now 'dpk'
* Some more random syntax cleanup fixes
* Say 'yes/no' instead of 'ok/fail' in check-langs script
