fix InitCommand() (#285)

split modules/config

login_tasks.go should probably be modules/task/login.go,
but i didn't do that, as it still depends on the global
`Config` variable from the config module, see
https://gitea.com/gitea/tea/issues/158

rework InitCommand()

- make it error tolerant if $PWD is not a git repo (#200)
- don't force default login when repo flag is set (#191)

remove InitCommandLoginOnly()

Merge branch 'master' into issue-200-initcommand

improve docs

Merge branch 'master' into issue-200-initcommand

move config func and config task func to right place
