Problems with different case in 'screen_name'

Twitter (as most web services) does not care about the case of the username, this can give problems since the twitter_get_user_accounts() function uses that username (screen_name) to perform a join between twitter_account and twitter_user tables.

The solution is simple and it just needs to change the query in twitter_get_user_accounts() to do the comparison with all lowercase, like:

$sql = "SELECT ta.*, tu.uid, tu.password, tu.import FROM {twitter_user} tu LEFT JOIN {twitter_account} ta ON (LOWER(tu.screen_name) = LOWER(ta.screen_name)) WHERE tu.uid = %d";
