#3 Wavesurfer doesn't respect the ttk::theme selected on the system level

[Géballin]

When launched for the first time, Waesurfer doesn't respect the ttk::theme selected by the user at the system level (on ~/.Xresources) and instead, set it's theme to the old looking default.
There is no reaso to not keep the theme selected by the user.
