fix getopts: handle -h --help bug fish-shell#746

Fix getopts multiline

Fix for bobthefish ruby version segment

… when there's no version to show.

Fixes #370

Change tiny declared globals to local scope.

Two fixes for tab plugin

iTerm2 nightly has an improved scripting bridge that exposes sessions, but until that ships, we'll have to use a hardcoded default and let users override.

Add tab plugin.

This is a port of a bash function I wrote almost five years ago:

The fish version is better though ;)

I only have OS X with iTerm and Terminal to test on, but it should be possible to add support for other terminals on other OS. Send a pull request!

Add tiny to plugins README

add new plugin: tiny

tap into github's git.io URL shortener
 e.g., tiny -u username -r repo -> http://git.io/be1iX

Fixing 'RVM is not a function, selecting rubies with 'rvm use ...' will not work.'

Add pbcopy plugin. OSX's pbcopy and pbpaste for Linux.

Autojump is no longer a plugin

README simplification.

Adding information to not add the screenshot to git.

`RBENV_ROOT` can be used to relocate where rbenv ends up storing the shims
and versions of Ruby it installs. Because of this split `RBENV_ROOT`
cannot be used to reliably construct a path to the rbenv binary itself.

Instead we now rely on `$RBENV_BIN_ROOT` pointing to the `bin/` directory
containing the rbenv binary/script.

If `$RBENV_BIN_ROOT` is not set we search `$PATH` first and then the
user's home directory making sure to prepend the necessary directories to
our `$PATH` depending on where we find rbenv.

Lastly we prepend to our `$PATH` the location rbenv's `shims/` so that we
can find the shims rbenv generates for us.
