Improve data type mapping feature
Allow set field type mapping / rules by CHARSET
Ex: if db field charset is UTF8 set field as TWideStringField
set field type mapping / rules by DOMAIN
Ex: if db field domain is DM_BOOLEAN set field as TBooleanField
[Optional] Separate TFieldMappings component that allow to define custom field mappings. TConnection/TQuery should have a property of this type.
Useful when use multiple connections (for example in threads), to define mapping rules once and link all Connections to one common component.
The first and the second features have been implemented.
