Release 1.5.0

Features

• vimagit is now able to handle multiple git repositories (fix #44,#34,#29).
• add mappings N and P to jump to next and previous hunk (fix #25).
• reorder magit display: display modified files first.
• disable inline help by default (fix #46). It is always possible to switch
  inline help display with 'h', or with g:magit_show_help
• rework magit buffer color syntax.
• display commit mode in Info section.
• rename magit buffer, now named after git repository path, e.g.
  magit:///path/to/git/repo/
• add MagitOnly command. It can be used to craft a bash alias like:
  alias magit='vim -c MagitOnly'

Fixes

• safe and smart handling of quit command (fix #41,#43).
• close vimagit window if there is another window.
• switch to alternate buffer if any.
• close vim if magit buffer the only buffer.
• disable ':w' mapping, which was not safe. This feature will be re inserted
  with a safer method later.
