#345 Display project-local options at top of ctrl+space list

[Gunnlaugur Thor Briem]

When I type e.g.

logger.debug("foo")

and then find that logger is highlighted red, "undefined variable", I go to the end of logger and hit ctrl+space in order to auto-add the import. The logger definition I want is in another file in my project. That import option does appear in the ctrl+space list, but not at the top of the list; the logger variable in the cookielib module appears at the top (presumably just because of alphabetization)

Name definitions in other files of my own project are likely what I intended, when I type a reference to an undefined variable. So for usability, those should be placed at the top of the list, perhaps with a separator between them and the rest of the options.
