Consistently use of {faq} notation to access the db table

For all drupal installations where a prefix for the table names has been configured, the {faq} notation has to be used instead of faq everywhere the database is accessed.

I've made following changes to the faq.module file to get the module running on my site using table prefixes:

130c130
< db_query('INSERT INTO faq (fid, weight) VALUES(%d, %d)', $node->nid, $node->weight);
---
> db_query('INSERT INTO {faq} (fid, weight) VALUES(%d, %d)', $node->nid, $node->weight);
137c137
< db_query('UPDATE faq SET weight = %d WHERE fid = %d', $node->weight, $node->nid);
---
> db_query('UPDATE {faq} SET weight = %d WHERE fid = %d', $node->weight, $node->nid);
