Added add-zsh-hook support to themes

I added add-zsh-hook support to the themes that didn't have it already.
This allows the themes to co-exist with plugins and lib/termsupport.
Added option to disable the update prompt. Set DISABLE_UPDATE_PROMPT to true to enable.
Use printf rather than echo -e in update.sh

update.sh is an "sh" script, not a zsh or bash script. On platforms
which have real sh, echo does not have the -e option.
set fpath correctly for custom plugins

Custom plugins weren't being added to the fpath correctly.
Moved ZSH_CUSTOM declaration before fpath is set

* also normalized style to match the guide.
Add the --format tag to knife list commands

This commit adds the --format tag to all of the autocompletion functions. The default format changed from json to a "human readable" format as of version 0.10.  This change should be backward compatible.  Alternatively, these commands could be simplified by using the new default human readable format.
Update theme

Use different colors in case of root or ssh connection for prompt.
Only alias git=hub if `hub --version` works.

`hub` is crashing for me on a old CentOS setup with
"undefined method `shelljoin'".

On first use of the `git` function it is now checked if
`hub --version` returns successfully.
