Autocomplete for Authoriser field in Vehicle Assignment

Both commit works fine locally. 

I think autocomplete commit is ok, but the other commit : DB migration rv & iv no for uniform stock received & uniform stock search  -  same problem arise before - db migration (rails g add_colums.....) created in Windows (git replace LF with SLRF for DB migration).   (previous commit with same problem : Fixes on Vehicle Assignment & Vehicle Release Order - DATED 24 March 2014)
