Bug#479851: qt4-x11: should use external webkit library

[Michael Gilbert <michael.s.gilbert@gmail.com>]

Package: qt4-x11
Version: 4.4.0~rc1-5
Severity: important

qt4-xll should use the already-packaged libwebkit-1.0 library, rather than
repackaging webkit separately.

this has a couple major advantages.  it reduces duplicated data (on the
debian archives, on the user's system, and in memory).  also, it reduces
duplicated maintenance overhead (only one maintainer needed to support
the single code base).  and finally, only one package needs to be
updated to fix security issues (see CVE-2008-1025 [1] where the webkit
library already has the fix, but qt4-x11 remains vulnerable).
