Subject: [PATCH] LibWebView: Add method to remove all cookies globally

The inspector widget has this functionality, but it's limited to the
site you're currently viewing. This commit adds an option for removing
all cookies globally.

Previously, the workaround was to open a sqlite shell and run:
`DELETE FROM Cookies;` on the database yourself.
