scripts: Add queue to vidl

Added queuing to vidl downloader - will collect newly added files to
download to a queue.
(by default in ($XDG_DATA_HOME/ or ~/.local/share)/vidl/vidl_queue)

The queue of links can be interacted with like any other file.

When vidl is already running it keeps a lock-file active in .cache
directory so only one instance of vidl can ever be running
simultaneously.
