Memorise is in the vortaro but memorize is not.

Scratch:Memorise is in the vortaro but memorize is not.

I've just added 'memorize'. Also changed the translation to:

memorise/memorize = enmemorigi, parkerigi

- the Lernu-vortaro also included the form 'parkeri', which can indeed be found in the Tekstaro, but all the dictionaries I looked at prefer the form 'parkerigi' (Wells, vortaro.net, Kondratjev, ReVo).
