Description

All funcs meant to be called directly with MsgCall must be crossing. This means:

1. Exported but non crossing funcs should always be called with a qeval; ie getters
2. If a func is called with MsgCall but it does not have the first argument of type realm, the response error message to the user should be along the lines of {funcName} cannot be called with MsgCall (/directly). It can either be called with qeval, or via another code realm.

Currently, the keeper spews an error that doesn't make sense to the end-user.
