Add new option to ignore match threshold for partial matches #109
Description
If a species name cannot be matched, the TNRS may still return a partial match on the genus. For some users this is a useful feature. However, because partial matches will generally have low overall match scores due to the unmatched epithets and possibly authors, the default match threshold of 0.53 often causes partial matches to be hidden, even when the partial match is a perfect match, at rank.
To address this issue, I suggest we add a new option "Allow partial matches below threshold". This would be a On/Off toggle button below the Sources option. Default setting would be off. If set to on, the match threshold filter would be applied only to results that do not contain the string "%partial%" in the plain English warning column. Partial matches would not be filtered.
