cubrid pdo does not support PARAM_BOOL so we cast the value to integer
and store 0 and 1 instead

fixes #964

fixes #854

fixed expected quoting

http://jira.cubrid.org/browse/APIS-658

bit has special syntax for storing and retreiving so we'd need a
converter for that.
Storing 1 bit will result in one byte left padded on the disc so the
result of a query for boolean 0 will be 0x00 and for boolean 1 will be
0x80.
