### Description
Implements the function `winview` which switches the visible tags to the tags on which the current client is visible.

This patch is inspired from <https://dwm.suckless.org/patches/winview/>. Citing the description of the dwm patch:

> Dwm tags are a powerfull feature that allows organizing windows in workspaces. Sometime it can be difficult to remember the tag to activate to unhide a window. With the winview patch the window to unhide can be selected from the all-window view. The user switches to the all-window view (Mod1-0), selects the window (Mod1-j/k or using the mouse) and press Mod1-o. The key Mod1-o switches the view to the selected window tag.
> 
> #### Recommend patches
> 
> The grid layout is well adapted to display many windows in a limited space. Using both grid and pertag patches you will be able to select this layout for the all-window view while keeping your preferred layout for the other views.
> Configuration and Installation
> Using the default configuration file
>
