Feature request: import exclusion/inclusion by directory

[kokizzu]

the case, when there are a lot of libraries in GOPATH/src, the autocomplete shows too much unused library:

It would be nice to add exception directories,
or better way GOPATH and list of directories to be autocompleted within GOPATH

most cases I only need certain <10 libraries (from hundreds that available on GOPATH)..

One possible candidate for exclusion should be the directory called Godeps. The nature of godep tool will make it to duplicate things. There's already a ticket to support godep workspaces at a later time after 1.0.

I'll try and investigate other package managers as well to see if we can eliminate by default directories.

Exclusions are added in 460 alpha build
