feature request: automatically put window on previously placed workspaces

[calendulish]

it would be an awesome feature to have, windows "magically" back to the workspace you put them. currently I must have a config line to each window that I want to be opened on a specific workspace, wouldn't need it anymore.

this could be done saving a list of which window is previously opened/moved in each workspace, and when a new window is opened, restore it to the workspace found in the list.

it would also solves #79. you could add a single check on the GlazeWM initialization to go through the previous saved window list of all workspaces and manage the ones that were found, restoring them to it's workspace.

for those who don't like this behavior, it could have a boolean configuration to restore all windows to the first workspace instead the previously placed workspace, still fixing the undesired behavior on crash.
