Summary: primary key generation support

Initial Comment:
Entity element is allowed to have entity-command 
element of the form:
<entity-command name="CommandName"
                class="ComandClass">
   <attribute name="attr1">value1</attribute>
   <attribute name="attr2">value2</attribute>
</entity-command>

where only name attribute is required; others are subject 
to override.

The commands were introduced to support different 
ways of creation primary values for entities.

The list of available commands specified in entity-
commands elment in standardjbosscmp-jdbc.xml. The 
default command is specified in standardjbosscmp-
jdbc.xml in defaults element.

Each entity can override the entity-command in defaults 
by specifying its own entity-command.

The role of overriding:
- entity-command's in entity-commands element contain 
a full command setup;
- entity-command in defaults can override class or each 
attribute of the command in entity-commands by 
supplying 'class' or 'attribute' element;
- entity-command in entity element can override entity-
command in defaults or the one in entity-commands 
element.

Also a new element <auto-increment/> now available in 
cmp-field element.
