Position Main inventory & magic menus

[GalumphingCallooh]

Hi, I'm trying to add positioning options for the primary inventory & magic menus (useful for Oculus Rift users); first time ever w/ Skyrim modding, papyrus scripting, etc, but I've managed to get as far as the attached commit (https://github.com/MrFancyMonocle/skyui/commit/00d254130a01dbf1a3d08eceb5e850b447377472). When I run the JSFL build script I'm receiving a wall of errors (somewhat attached). Anything to point me in the right direction or simply dismiss this as a fool's errand would be greatly appreciated. What am I missing?
