Support conditional parameters (f:param)

[janario]

Sometimes it easier to build urls with conditional f:param
For example, usually I have some links with css styles and customization like:

<pretty:link mappingId="page" >
<i class="style"/>
<f:param value="#{myparam}" disable="#{not myLinkRequireParam}"/>
</pretty:link>

But once 'disable' is not verified pretty:link will always add it and fail for mismatch parameters
Then I have to do something like: (and always remember to change all links when change one of them)

<pretty:link mappingId="page" rendered="#{not myLinkRequireParam}">
<i class="style"/>
</pretty:link>
<pretty:link mappingId="page" rendered="#{myLinkRequireParam}">
<i class="style"/>
<f:param value="#{myparam}" />
</pretty:link>
