[TYPO3] real url + set and remove parameter

[PEF]

Think I've got the answer. I've allready got a cObject with params, so I 
just added an extra param to this structure - and then:

lib.altLink.typolink.additionalParams.cObject.80.value = &alt=1
[globalVar = GP:alt > 0]
   lib.altLink.typolink.additionalParams.cObject.80.value = &alt=0
[global]
