[lojban] multiple translations

[Pierre Abbat <phma@webjockey.net>]

I added {selratni}, {cmuxu'i}, and {xu'icmu}, all of which are appropriate 
translations of "element;chemical", to jbovlaste. They all are true of the 
same x1 (except that one may argue that lo solnavni na xu'icmu da), but have 
different place structures and are used in different contexts:
lo'e kliru cu selratni fi reda
.i le vi kliru cu cmuxu'i fi li 99%
.i lo kliru cu xu'icmu le silna
So which should be the translation in jbovlaste?
