Main library should use ZSH native hostname function

This is needed to play nice with plugins that need various hooks.

After a few weeks of using this, I'd prefer this to not be enabled by default. My bad for suggesting that in the first place.

This reverts commit fc49b4a4.

The command C-x C-e opens the current command line for editing
in the editor defined by the $EDITOR environment variable.

Thanks to Craig Bosma and his blog post about this:

Changes method git_parse_ahead() on git.zsh lib file. Before this
change it checked directly against origin/master branch. Now it
uses $(current_branch) to check for not pushed changes against
the current remote branch.

Modifies the Git lib file (lib/git.zsh), adding three new prompt
methods:

- git_prompt_ahead(): Shows the content of the custom var
  $ZSH_THEME_GIT_PROMPT_AHEAD if the local repository has
  commits ahead from the remote origin repository

- git_prompt_short_sha(): Shows last commit SHA hash in short
  mode wrapped between the content of the custom vars
  $ZSH_THEME_GIT_PROMPT_SHA_BEFORE and
  $ZSH_THEME_GIT_PROMPT_SHA_AFTER

- git_prompt_long_sha(): Shows last commit SHA hash in long
  mode wrapped between the content of the custom vars
  $ZSH_THEME_GIT_PROMPT_SHA_BEFORE and
  $ZSH_THEME_GIT_PROMPT_SHA_AFTER

This reverts commit c3a58b00.

Fix by derekjw. closes #52.

Closes #45 #57 #58 #86.

Was causing iTerm title to disappear entirely..

This reverts commit d4ea399b.

doesn't support tabs titles.

Term window title and tab title are now skinable
Tab title can be different from window title (when supported by term)
Default theme is optimized of usuability (no %u@%m: $~ in a 10 char tab)
Cleanup code duplication and add comment for supported terms
On osX it works great on iterm, and is decent once you tweak Terminal pref
Tested under GNU screen, iTerm and Apple Terminal, need to be tested on linux
TODO implement Konsole support (via dbus)

Also an alias for the function.
