commit FS#9027 - conditional viewports

** BREAKS CURRENT WPS's  **
* %P has been removed, merged with the new %pb
* %pb is now %pb or %pb|bitmap|x|y|width|height| (any of those params can be - to use sane defaults... check wiki/task for more explaination)

* New %Vl and %Vd tags which are used to setup and display conditionaly displayed viewports (%Vl|<id>|<usual %V params>| to set up, then %Vd<id> to enable the viewport
* bumps the max allowed viewport count to 24
* you can setup 3 different progressbars in a WPS... max of one per viewport though

http://www.rockbox.org/tracker/task/9027?getfile=16785 is a simple perl script to convert old %P/%pb to the new %pb syntax

I'll commit changes to the cabbie wps soon which shows how to use %Vl/%Vd properly...

Reminder: %m will be removed soonish also so when fixing your WPS's remember to use conditional viewports to replace %m
