Update to vimperator-1.4.2.

Changes:
1.4.2
=====
- Bugfix for mapping

1.4.1
=====
- Bugfix for "map d" (patch by desyncr)
- Amending the missing man page documentation for the new settings
  introduced in 1.4.0

1.4.0
=====
- Shortcuts function (Hannes Schueller)
This is basically an extension of the search engine feature.
Shortcuts can have one or zero string placeholders, making it
possible to use these definitions as a sort of extension of the
limited quickmark slots. The definition in the rc file goes just like
the search engines before. Mind that the keyword "searchengine" in
the rc file will continue to work for now, but its use is
deprecated in favour of using "shortcut" (as per the man page)!

- Download path, status bar font, URL box font and completion
font are all configurable via :set (Matto Fransen)

- Support for different cookie policies: accept all cookies
(default), accept no third party cookies or accept no cookies. This is
configured using the "cookies" setting:

 :set cookies=(all|no third party|none)

Mind that this will not affect cross domain requests!
The policy is always evaluated with respect to the atomic HTTP
request. I.e. if website example.org embeds contents from example.com
in an iframe or in an image tag, cookies from the latter will
still be accepted in the "no third party" setting if they are
delivered with the contents in the iframe/image tag. No correlation
between hierarchical requests like this is performed.
Tested with wip/webkit-gtk... Convert the package back to www/webkit-gtk.
