added Makefile and simple Bash completions

 * this allows precompiling openrussian.lua,
   automatically downloads, converts and VACUUMs the openrussian
   database and provides an `install` target
 * Bash completions allow completing "bare" Russian words for the
   time being.
   Unfortunately we cannot complete with accents, since Bash completions
   do not allow to change the already typed word (apparently) and users
   aren't going to type in accents.
