Go bash completion

this is a work in progress, still considering other ways to implement things

Initially this bash completion is based on the one removed from the go repository.

Added features

Cache of go package list

Output of "go list all std" is stored inside an environment variable, so it's on a per shell level. Having The _go_clear_cache function clears the cache if needed.

Alternatives

These are all the current alternatives I've found.
