phpnut 8ab148a598 Merging fixes and enhancements into trunk.
Revision: [2087]
Removed array setting that is not needed

Revision: [2086]
Added unbindModel to turn off associations on the fly.
These are reset after a call to a find<*> method.
Added one more level key to isset check in DboSource::conditions.
Previous check would always return true.

Revision: [2085]
Refactored DboSource::fields()

Revision: [2084]
Added fix for Ticket #419    

Revision: [2083]
Refactoring DboSource::conditions.

Revision: [2082]
Deleted a few methods by accident adding them back

Revision: [2081]
Added fix for Ticket #420
Added $startQuote and $endQuote vars to the MySql class, these must be added to each Dbo<database> if the database uses
a quote char around fields. Example MySql uses this ` MSSQL uses [ and ].

Revision: [2080]
Added delete() alias for del() in Model and SessionComponent classes.
This is suggestion from Ticket #421

Revision: [2079]
Added fix for Ticket #106.
This was added before but lost in a merge.
This fix allows adding a custom tags.ini.php file to app/config.
This file will be merged with the core, overwriting any keys that match, and adding those that do not.

Revision: [2078]
Refactoring DboSource::conditions().

This method will now return the Model.field properly when passed a string.
You can also set you own clause.
WHERE, GROUP BY, HAVING, and ORDER BY.
If one of these in not the first characters in the string, WHERE will be added by deafult.
