Updated install script

Removed Jekyll template option - it does not really belong in Bash-it.

Removed the all/some/none options. Most people selected `all` and then
complained about things not working, or error messages being shown. This
was mostly due to missing dependencies.

The installer now uses a 'sane' default - it just enables completion for
the 'bash-it' command and nothing else. At the end of the installation,
it prints a message explaining the ways to see the available plugins and
how to enable them.
