Enhancement: try_import()

[bokov]

I'm not super keen on trying to parse with every imaginable import function. That might produce some kind of unanticipated weird behavior if one of those underlying functions changes to start supporting different kind of file or if we add future functionality that changes the deterministic order of import attempts.

We could add a separate function that does that, though, like try_import().

Working my way toward try_import(), first I'm submitting PRs for additional helper functions like isfiletext() in #239. Those will permit try_import() to be smarter about which import functions are tried and the order in which they are tried.
