Support for relative dates in filter

[bmmsea]

Description

Add support for relative timeframes in the Release Date filter, also interpreted as part of the URL search itself so that it can be bookmarked.

Desired Behavior

When entering date filter criteria, allow the To and From to use "30 Days" or "1 Years" or "N timeframe" relative to the current date.

To: Interprets forward
From: Interprets the time window as back from the current date

Additional Context

Use case: Create a bookmark with movies released in the last year, or movies that will come out in the next 30 days.

as a user I like this idea but where would you even wanna see these options without cluttering up the UI too much?

[bmmsea]

The current From and To fields would be sufficient. They currently allow for free form text input, they just don't do anything when they aren't a valid date. The UI doesn't need to change, just how the values are interpreted when applying the filter.
