make tabs in optionsdialog and userinfodialog scrollable

[fabian2_de]

I really very like the feature to scroll tabs with my mouse, so here are the patches for the other tabwidgets used in licq:

/plugins/qt-gui/src/userinfodlg.cpp

121c121
<   tabs = new QTabWidget(this);
---
>   tabs = new CETabWidget(this);

/plugins/qt-gui/src/optionsdlg.cpp

71c71
<   tabs = new QTabWidget(this);
---
>   tabs = new CETabWidget(this);

Well, as you can see, my work isn't noteworthy... the thanks goes to Erik, who did this great improvement! Thank you very much!!
