Set the level for this entry

Check if first and firstplural have been use. If firstplural hasn’t been specified,
but first has been specified, then form firstplural by appending \glspluralsuffix
to value of first key, otherwise obtain the value from the plural key. This now
uses \ifx instead of \if to avoid expansion issues. (Thanks to Ulrich Diez for
suggesting this.)
