Luke Wilde e04ec39984 Ladybird: Start applying the default content filter 
For the first cut, the file path is not configurable and the content
filter cannot be toggled on or off. If we fail to apply the content
filters for any reason (e.g. the filter file doesn't exist), we simply
just stop loading the content filters to allow using Ladybird without
content filters.
