Patch for ticket #479 - Change user's picture with Drag&Drop

[Mentos]

i have created a patch for the ticket #479 (http://trac.kmess.org/ticket/479)

works fine with the picture in the contact list, in chat window, and works also for the picture of other contacts.

But to do this i had to duplicate some code from accountpage.cpp related to the picture's creation, and between pictures for drag&drop handling .

Suggestions?

Also, i've fixed a little bug: changing the contacts' pictures with an own image (and viceversa) the pictureChanged() signal was not emitted, and the existing picture in chat window was not updated.

This is very very nice! I'll check and commit this patchset right now :O Thank you!

For 2.1 the codebase is quite better, we have a widget dedicated to showing DPs; we could add a Contact reference to self or a contact to it, to enable this same feature quite more easily

(ps this means this code can't be committed to 2.1 as well as 2.0.x)
