lookup: do not bail on first failed lookup with a word list

Browse Source 
Due to the lack of deinflection support in StarDict, users might want to
be able to create a list of possible deinflections and search each one
to see if there is a dictionary entry for that deinflection.

Being able to do this in one sdcv invocation is far more preferable to
calling sdcv once for each candidate due to the performance cost of
doing so. The most obvious language that would benefit from this is
Japanese, but I'm sure other folks would prefer this.

In order to make this use-case better supported -- try to look up every
word in the provided list of words before existing with an error if any
one of the words failed to be looked up.
