testing: add -outputdir flag so "go test" controls where the files are written
Obscure misfeature now fixed: When run from "go test", profiles were always
written in the package's source directory. This change puts them in the directory
where "go test" is run.
Also fix a couple of problems causing errors in testing.after to go unreported
unless -v was set.

misc/vim: Adding flag-guarding for Vim commands

Default behavior is the same as before, but now a user may selectively disable some commands.

Also: deleted the mappings for import.vim.

Tested: by trying the commands for fmt, import and godoc in succession to make sure they still work. Also, ran test.sh in ftplugin/go.
