SQL fails with enabled table-prefixing

problem:
- SQL in funktion regcode_load() fails with enables table prefixing. Error occurs at insertion time of voucher code on user profile.

- current implementation:

'SELECT term_data.tid, term_data.name
FROM {regcode_term}
JOIN {term_data} ON (regcode_term.tid = term_data.tid)
WHERE regcode_term.rid = %d'

- bugfix:
'SELECT term_data.tid, term_data.name
FROM {regcode_term} AS regcode_term
JOIN {term_data} AS term_data ON (regcode_term.tid = term_data.tid)
WHERE regcode_term.rid = %d'
