Contao 4.12+ compatibility

[fritzmg]

This extension will no longer work with Contao 4.12+ (see contao/contao#2917). To fix this it needs to implement its own search module.

[gmpf]

Wouldn't it make sense to add a constraint to composer.json to reflect the incompatibility for as long as it lasts? Like, instead of ^4.4, have >=4.4.0 <4.12.0 or something to that effect.

With regard to a broader outlook, it would be really cool to have a hook in the core that would allow for filtering of search results. I know that wouldn't solve the issue for ^4.12, but it would be a lot better than having to copy the entire module in a bundle or add a patch in an application.

That won't matter as a version that is unlocked for Contao 4.12+ has already been released.

Oh, yeah, that's right, that version would always be picked then, never mind. :/
