Allow the Member in class: prompt to be easily skipped under ido-mode

Context

When using completion for Java interop, one normally browses the options by repeatedly pressing <down> or <up>.

However, if one completion is ambiguous (as for its Java class) we will perform a completing-read. Sample:

This completing-read breaks the user flow. Say I want to press <down>, <down> (go two candidates down). Then after the first candidate, the completing-read will interrupt the experience.

One can only exit this pressing RET (to choose an arbitrary one) or C-g. Both require excessive awareness of what's going on and how to remediate it.

Also, ambiguity happens quite often, so requiring users to press <down>, RET once for each ambigious candidate is a pretty irritating experience.

Proposed solution

Temporarily redefine the up and down keys to mean 'abort'. This way, completion can proceed.

Only ido-mode is affected. Other modes can be tackled in a future.

I've tried this and it works as intended.

Reflecting a bit, while this works, perhaps it's excessively risky to modify things just for a single combination (Company + IDO).

Maybe we can provide the primitives, and document in https://docs.cider.mx/cider/usage/code_completion.html#auto-completion how to wire them up (or write your own, if needed?)

I agree - it's best to leave this to the users to do it if they want to. It's generally not a good idea to optimize for any particular tool, and a combination of tools is even worse IMO.
