Whisker Menu 2.10.0 released

I made a new release of Whisker Menu today, but users won’t be able to tell. 😛 That is because this release is just for switching to the Meson build system to match the rest of Xfce. There were a few minor source fixes related to that, but no functionality changes. I will be removing support for CMake in the next feature release, but it will hang around for the rest of the 2.10 releases.
