Improved CLI's flags and changed help page (#341)

* Improved CLI's flags

Allowed users to use just --v instead of --version as a CLI flag. Also added in the --name flag that simply prints out "Browsh." An alias for the --name flag is --n.

* Changed the help page inside the config.go to include the name flag
