Add Foreign Keys / Change Names

[Pauldro]

Add the following Foreign Keys

Current Name	New Name	Foreign Key
SalesOrderNotes	SalesOrderNote	SalesOrder
SalesHistoryNotes	SalesHistoryNote	SalesHistory
QuoteNotes	QuoteNote	Quote
PurchaseOrderNotes	PurchaseOrderNote	PurchaseOrder

For the Current Class, Remove the _Base_ and _Map_ Files for it

Then rename the _Model_ class and replace _Base_ to match
Ex. SalesOrderNotes.php will now be SalesOrderNote.php and in the file will extend Base\SalesOrderNote

Make one commit for each Foreign Key addition remember to download the _Base_ and _Map_ for the new Class and the Foreign Key class.
