Cannot use boat after being affected by "addled" (vescavor)

[BlackJar72]

After being addled by a vescavor the keyboard controls will not work for steering a boat. This lasts until the players logs out and back in again.

Apparently the normal control binding for steering boats (horses? other things?) are now separate from normal movement -- these are lost when addled to be replaced by backward version and need to restored separately. (Just an initial guess.)
