Make windows floating before moving them to origin workspace.
2021.10.19

Use workspace name when appropriate.
2021.10.18

Fixed issue with calculating the next free workspace.
When the zencontainer is created, if the last window of a workspace
is used to create it. The current workspace will be the zen workspace.
2021.10.17

This script depends on i3list and i3var from i3ass.
When the command is triggered it will move the current window
to a zen container. The zen container is a floating,
tabbed, and zentered container on a clean workspace. If no zen
container exist it will be created.
If the current window already is in the zen container it will
get moved to the workspace it originally came from.

The previous version used two "ghost windows" to make a tiled container
appear centered. But i figured why not use a floating container instead, script
is a lot faster and experience better. Now it is also possible to set the height
(also in percentage) of the container.

Available environment variables:
ZEN_WIDTH , ZEN_HEIGHT, ZEN_WORKSPACE, ZEN_VERBOSE
