* new: qualifiy each column name with the table name using DibiResult::setWithTables

* removed DibiResult::setType(TRUE) with autodetection
* removed DibiResult::getFields() & getMetaData() in favour of new method getColumnsMeta()
* MySQLi and MySQL transaction implementation are the same
* better escaping in DibiPostgreDriver (new pg_escape_string and addslashes)
