AgaviEqualsValidator's docs do not match the actual validation process

[morkai@…]

The doc comment of AgaviEqualsValidator states:

 * When the parameter 'asparam' is true, the content in 'value' is taken as a
 * parameter name and the check is performed against it's value otherwise the
 * content in 'value' is taken.

but the process() method doesn't use the asparam at all.

To make it work currently, one has to write:

<validator class="equals">
  <arguments>
    <argument>password2</argument>
    <argument>password</argument>
  </arguments>
  <error>Passwords do not match</error>
</validator>

but when validation fails, error message is added to both fields.

With attached patch, one can write:

<validator class="equals">
  <argument>password2</argument>
  <parameters>
    <parameter name="value">password</parameter>
    <parameter name="asparam">true</parameter>
  </parameters>
  <error>Passwords do not match</error>
</validator>

and error message will be added only to the field(s) specified as argument(s).
