Launch virtualenv directly

[ttimasdf]

I encountered several problems launching virtualenv in REPL. After read through the source I've found that it launch interactive shell from lines of code, in ipy_repl.py. This caused two problems:

• sys.path will not correctly include an empty string according to documentation, therefore can't search for module in the current working directory.
• up and down arrow key for command history will not work unless the cursor is in the last line. (work well after tested again)

Is that piece of work a little bit redundant? I'm confusing of what bugs it solves comparing to the bugs it brings.

My environment: OSX 10.11 with latest dev build of Sublime

Even with master branch it raised exceptions as well

***Repl Closed***

So maybe this script should be depreciated.
