Mebbeth and the Mage Quest

Problem:

A dialog trigger inside Dmebbeth.dlg has a full stop after the parameter, which gemrb doesn't like, so a smart mage will not be able to complete the quest

Reproduce it:

Go into the hut, say 'Here's that ink you wanted'. You will not be able to reply anything other than 'I don't think the art is for me'
