Two patches for tabbar

[Tomek]

Hello,

Below are two patches for tabbar:

1. Enable middle click on "new tab" button - this opens new tab with contents of the primary clipboard.
It partially helps with https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192748.

2. Mouse scroll on tabbar changes tab (I don't know if it is really needed but it is default on linux)
