No suggestions/completion in import paths

[ahmetb]

If I create an

import ( )

block and start typing

import (
    "github.com/...
)

it should suggest me the packages in GOPATH. GoSublime does that well.

This would be nice - but is something that would really have to be supported in gocode to make sense. Looks like there's a feature request for this here: nsf/gocode#257.

For now though, I've added a couple new features to support this per #53 (comment). I think that should be sufficient for now.
