Improve usability askCard() and similar functions.

[zz1000zz]

Currently askCard() matches a search string exactly. It would be useful if it could match by substring. This would enable things like searching for "Land" in a column that has both "Land - Forest" and "Land - Island" rather than having to write out every potential search case.

It may also be worth checking similar functions to try to make them all work in a more consistent (to one another) manner.

These functions are most likely going to change to dedicated classes in the next API revision, so game devs have better control over the inputs
