Search condition ids are now indexed from 0, and always saved
contiguously (no more 'fixGaps' option), since they're just in an array
in the API. (They're still returned as an object from
Zotero.Search.prototype.getConditions() because it's easier for the
advanced search window to not have to deal with shifting ids between
saves.)
- Make "Saved Search" a separate search condition from 'Collection' in drop-down menu
- Better handle invalid search conditions
- (Dev) Saved search conditions are now 'collection' and 'savedSearch' rather than 'collectionID' and 'savedSearchID', though the latter can be used as shortcuts when adding
This could use some testing.
