Faulty SQL query in insurge-client.php

Line 61:
two bugs:
1. if count of $bnum_arr is greater than zero, the first element may still be empty, resulting in a faulty query
2. even when corrected, for some reason the function gets the search type, not bnum scope as an argument, resulting query:

_doQuery: [Error message: Could not execute statement] [Last executed query: SELECT tag, count(tag) AS count FROM insurge_tags WHERE group_id = "YOUR GROUP ID" AND bnum IN (keyword) GROUP BY tag ORDER BY count DESC LIMIT 500] [Native code: 1054] [Native message: Unknown column 'keyword' in 'where clause'] 1
