New theme: Gianu Theme

I created a theme that I feel confortable with and want to share with
everyone.

The prompt format is: <user>@<host> <current_dir> (<git_status>)$

themes/gianu.zsh-theme

+# Oh-my-Zsh prompt created by gianu

+PROMPT='[%{$fg_bold[white]%}%n%{$reset_color%}@%{$fg_bold[red]%}%m%{$reset_color%} %{$fg[cyan]%}%c%{$reset_color%} %{$fg_bold[green]%}$(git_prompt_info)%{$reset_color%}]$ '

+ZSH_THEME_GIT_PROMPT_PREFIX="("
+ZSH_THEME_GIT_PROMPT_SUFFIX="%{$reset_color%})"
+ZSH_THEME_GIT_PROMPT_DIRTY="%{$fg[green]%} %{$fg[yellow]%}✗%{$reset_color%}"
+ZSH_THEME_GIT_PROMPT_CLEAN="%{$fg[green]%}"
