[dev] config / xml

[Marko Djukic]

not really sure of the correctness of doings something like this, but what if in
the conf.xml files when there is for example:
   <configenum name="phptype" desc="What database backend should we use?">mysql
    <values>
     <value desc="MySQL">mysql</value>
     <value desc="PostgreSQL">pgsql</value>
     <value desc="ODBC">odbc</value>
     <value desc="Oracle">oci8</value>
    </values>
   </configenum>

the <values> or whatever else is between the <configenum> </configenum> tags is
read by default as the params parameter of the addVariable() function. rather
than doing tests for enum, multienum.
this means that we could do something like this as well:
   <configlongtext name="somevar" desc="Sometext">
    <rows>4</rows>
    <cols>60</cols>
   </configlongtext>

or whatever the right XML syntaxt would be for doing something like this...
