Update README formatting

Fixing some issues where show repeated weird values, and fixed commands that need the container autocomplete without being running, like start, now it autocompletes showing all the containers so you can start without knowing the right name

Added support for `tcpip` option

This patch will re-order the if statements when checking what operating
system the user is running.

This is useful for people that already have a `notify-send` binary in
their $PATH but are running OSX. An example of such requirements is
anyone running `vagrant-notify` is required to have a `notify-send`
binary on their $PATH.

See [link](https://github.com/fgrehm/vagrant-notify#os-x).

Removing say() function in perl plugin so that it doesn't overwrite OSX comand line utility. Closes #2562

If a user sets ZSH_THEME_HG_PROMPT_* as the following, he ends up with
%{$reset_color%} resetting the bold style of last character ")" because
_SUFFIX was expanded before calling hg_dirty():

    ZSH_THEME_HG_PROMPT_PREFIX="%{$fg_bold[blue]%}hg:(%{$fg[white]%}"
    ZSH_THEME_HG_PROMPT_SUFFIX="%{$reset_color%}"
    ZSH_THEME_HG_PROMPT_DIRTY="%{$fg[blue]%}) %{$fg[yellow]%}✗%{$reset_color%}"
    ZSH_THEME_HG_PROMPT_CLEAN="%{$fg[blue]%})"

With this patch, the variable ZSH_THEME_HG_PROMPT_SUFFIX is lastly
displayed, following the same order as in git_prompt_info(),
i.e. <prefix><dirty><suffix>.

Allow ctrl-h, ctrl-?, ctrl-w after changes in normal mode.
