Configure SysConfig prefix from 00_qi XML file

With this change, we don't need to create views such as PermissionsView
that just adds a constructor. One just needs to add three properties
to the view configuration:

   * name
   * title
   * prefix

i.e.:

    name: permissions
    title: Permissions
    prefix: perm.

full example:

  <view route="permissions" class="org.jpos.qi.sysconfig.SysConfigView" perm="sysadmin" sidebar="system">
    <property name="entityName" value="permission"/>

    <property name="name" value="permissions"/>
    <property name="prefix" value="perm." />
    <property name="title" value="Permissions" />

    <attribute name="id" read-only="true" required="true"/>
    <attribute name="value" regex="&TEXT_PATTERN;" required="true"/>
  </view>
