Added configurable List Table Column character limits

[tomsb]

Extending the controller would be easy, but I feel that's overkill for this functionality.
What do you think?

Hey @tomsb thanks for the PR.

I think in this case extending the Controller is the right approach. In no time you will want another attribute, then someone wants other, and we will have created a bunch of configs for field attributes.

Most of the time, if not every time, you would want to add new settings etc.

One thing we could think about is to make this package publish a class, like SettingsControllerDefinitions with the defaults (fields, columns etc) defined, and you can just change/add/remove the settings fields there.

The pro is that the SettingsCrud in this package would read that class to define the fields/columns, so you don't need to overwrite the controller and bind your new controller.
The downside is that is a "different" way of doing things and it might look weird and overcomplicating something that's "easy" to do.

I am tempted to say that just overwriting the controller give you much more flexibility, plus it will look and feel like other backpack crud controllers.

What do you think ?

Cheers

Makes sense to just overwrite the controller. My main issue with it is that the default limit of only 32 characters for the description column isn't sensible - it's too short for a description. This could be hardcoded directly into the column definition?

Also, the LV translation somehow ended up in this PR - apologies for that.
