Merge my trunk-dev, with following mods:

* cd completer: show bookmarks if no other completions are available.

* Remove ipy_leo.py. "easy_install ipython-extension" to get it.
  (done to decouple it from ipython release cycle)
  
* sh profile: easy way to give 'title' to prompt: assign to variable
  '_prompt_title'. It looks like this::
      
        [~]|1> _prompt_title = 'sudo!'
        sudo![~]|2>
        
* %rehashx: Aliases no longer contain dots. python3.0 binary
  will create alias python30. Fixes:
   #259716 "commands with dots in them don't work"
  
* %cpaste: %cpaste -r repeats the last pasted block.
  The block is assigned to pasted_block even if code
  raises exception.

* %edit: If you do '%edit pasted_block', pasted_block
  variable gets updated with new data (so repeated 
  editing makes sense)

Test mods:
