added details, deathdate, hair color, weight to performers and added details to studios

[ghost]

I added a new column details on the table performers and studios.
I also changed the scrapper freeones to get the bio from the freeones's website.
I added it on is missing filter.
Resolves #811
Resolves #712
Resolves #545

Since it's doing a schema update for performers, perhaps consider including the following:

• Date of death ([Feature] Date of death field for performers #545)
• Weight (Performer profile page UI enhancements #124 (comment))

If we include Weight we should include Hair Color.

[WithoutPants]

If we include Weight we should include Hair Color.

Agree. Didn't see that in the github issues, but it is commonly asked for.

[ghost]

Are you as well included rating into performers's table as well?

[WithoutPants]

No. Rating needs more changes outside the basics, so should be raised as a separate PR.

[ghost]

Ok it is all done, I added deathdate, hair color and weight to performers. But one question before pushing, do you want me to add a filter death year into performers filters?

[WithoutPants]

Yes, filter criteria should be added for death date, hair colour and weight.

[ghost]

ok so I added deathdate, weight and hair color to performers, and even on filters.
I changed freeone's scraper to download the new data.

[bnkai]

There is currently no validation for the age. Could we add a simple one to make sure death_date > birthdate for the age display?

[ghost]

I added a validation for the date. And I added some tests.

[WithoutPants]

The weight field requires more design decisions. I'm not sure it's worth including in this PR.
