[TxMt] Pressing "O" in Git Blame

[Igor K]

Textmate gets frozen for 15 seconds and then throws 

```
JavaScript Warning

The command ‘ruby18 "/Users/igor1043k/Library/Application Support/TextMate/Managed/Bundles/Git.tmbundle/Support"/dispatch.rb "controller=log" "action=open_revision" "file_path=/Users/igor1043k/git/Bilbeo/Application/DataAPI/libs/models/Workspace.js" "revision=9201f304"’ has been running for 15 seconds. Would you like to stop it?

To avoid this warning, the bundle command should use the asynchronous version of TextMate.system().
```

This bug is very old and it looks like no one but me uses this feature. Maybe someone with ruby knowledge can fix this thing?

Thanks.
