- Use cobra in order to provide subcommands `serve` and `db`. - Subdir `cmd` is removed. - Subdir `cli` is created, which is a standard cobra structure. - Sources related to the core are moved to subdir `lib`. - #497 and #504 are merged. - Deprecated flags are added. See https://github.com/filebrowser/filebrowser/pull/497#discussion_r209428120. - [`viper.BindPFlags`](https://godoc.org/github.com/spf13/viper#BindPFlags) is used in order to reduce the verbosity in `serve.go`.
