Move Column logic from Twig to PHP

[stephanvierkant]

Currently Twig is used to render the options. I think Twig shouldn't be used like this: this is where PHP should be used instead. Related to #819. This is just a 'proof of concept', so please share your thoughts about this.

Not the most important or this idea, but the HTML will look better too:

I agree, options should not be generated manually from twig.

You only did it for columns options but I think this should be done for everything. (wip so I guess this is planned?)

I think:

• getTwigOptions should be renamed by getOptions.
• twig templates and getOptionsTemplate method should be removed

I've changed the method name and removed getOptionsTemplate

Since ColumnInterface has been changed, this is a BC-breaking change.
