The 'Remote Is Closer' Release

Almost two months since the last release, and with reason: I've been working hard to define remote()'s semantics. So far this is what there is:

• Global and current scope's local variables can be used in the remote code. This includes envvars.
• Changes to the local variables return to the local code.
• Execution is done synchronously.

I'll write a blog post soon explaining this in more depth. Meanwhile, check the full ChangeLog:

• Great improvements in remote()'s API and sematics:
  • Made sure local variables go to and come back from the remote.
  • Code block is executed synchronously.
  • For the moment the streams are no longer returned.
  • _python_only option is gone.
  • Most tests actually connect to a listening netcat, only one test uses ssh.
• Fixed bugs in the new parser.
• Fixed globals/locals mix up.
• Scripts are no longer wrapped in a function. This means that you can't return values and that module semantics are restored.
• ayrton exits with status 1 when the script fails to run (SyntaxError, etc).
