free start/final-time in XML

Description

When generating XML equations of an optimization problem where the finaltime (or starttime) is set to free, a binding equation for finaltime is generated to 1.0. Basically resulting in a normalization to [0, 1]. A side effect of this is that CasADi interprets, in this case, the finaltime to be fixed an replaces all occurences of finalTime to 1.0. If the cost function is dependent on the finaltime, it is converted to a constant, which is not very useful.

We need to consider how we want to handle a free finalTime or free startTime in the XML equations. And also how point constraints should be handle in the case of free start/final-time.
