phpnut 0c0dec8bc0 Merging fixes into the trunk.
Revision: [2629]
Fixed recursive associations when set to 0, did not add the hasOne or belongsTo in the query.
Changed scaffold to use recursive setting of 0 in all methods that call Model::findAll()
Fixed Invalid argument supplied for foreach() notice in show.thtml
Removed 500 record limit in Controller::generateFieldNames()

Revision: [2628]
Merging changes from model_php5.php

Revision: [2627]
Fixing messed up characters in dbo_odbc, adding docstrings, and giving connect() a return value

Revision: [2625]
Bringing all DB drivers up to date

Revision: [2624]
Changed fixed for Ticket #609 so and empty array is set instead of null.
This is more consistent with the other arrays that are returned if an association is found

Revision: [2623]
Adding fix for Ticket #712
