[TR] TR_Data mesh tr_ex_imp_gatejamb01 cannot be activated
This is a gate and supposed to open when activated. https://dl.dropboxusercontent.com/u/83265276/openmw-gate.jpg
It is a crappy model and has a useless KeyframeController and a bounding box collision (unusual and apparently not supported by OpenMW right now).
This is not #1107 (closed). Thanks to scrawl for help with debugging this; I hope that at least the KeyframeController will be gone next TR update.
