Added mercurial library

Browse Source 
The added library parses output of the hg (mercurial) command, and outputs
the same variables (which should be customized by theme) in your prompt.
I added an example of these variables to michelebologna theme.

This patch should uniform all the behaviour of all themes regarding mercurial.
In fact, some themes implement their own hg parsing *inside* the theme.
This should be better implemented in a library, as happens with git library.

# Michele Bologna
#
# Implements a hg_prompt_info function that inspect the current mercurial repo
# (if any) and then outputs the status of the repo, in a similar way with
# git.zsh library.
#
# themes should customize:
# * ZSH_THEME_HG_PROMPT_UNTRACKED - symbol to show in prompt if untracked
# files are present in the mercurial repo
# * ZSH_THEME_HG_PROMPT_ADDED - symbol to show in prompt if added files are
# present in the mercurial repo
# * ZSH_THEME_HG_PROMPT_MODIFIED - symbol to show in prompt if modified files
# are present in the mercurial repo
hg_prompt_info()
