card filter: alphabetical ordering for keywords

[tooomm]

Short roundup of the initial problem

Keywords used to be unordered.
Because of the missing logical structure it was difficult to quickly find the needed filter.

What will change with this Pull Request?

• Display filter keywords in alphabetical order
• Filter logic is ordered in the same way in the code now, too

Can these be sorted without reordering the cases of CardFilter::attrName in cardfilter.cpp? I don't mind them being alphabetically ordered in the source as well, but I'm also generally in favor of sorting with a .sort() call instead of doing it by hand—that way, future changes don't have to rigorously follow the same sorting, but would be automatically sorted.

@Nightfirecat I fully agree. This complicated change logs for no reason

[tooomm]

Only the few changed lines in cardfilter.h are the crucial ones for the displaying purpose here. I updated the PR accordingly.

If somebody comes up with a smart self-sorting solution and opens a PR, this can be closed for sure. 👍

Seems good to me
