Tweaks certain user preferences to use a row-based layout instead of a column-based layout. This includes various preferences in Viewport -> Quality, Navigation -> Orbit & Pan, and Navigation -> Zoom. To be specific, the Viewport -> Quality -> Smooth Wires, Navigation -> Orbit & Pan -> Auto, and Navigation -> Zoom -> Invert Zoom Direction preferences have been converted to use a row layout instead of the prior column-based layout. This should help cleanup the Preferences UI a little bit, as well as make it more compact.
Additionally, the internal timeout variables, texture_time_out and vbo_time_out have been renamed to texture_timeout and vbo_timeout respectively. The user-facing strings have been updated to reflect this change, and as the internal variables already use the updated names, the custom text for the two preferences have been removed from the User Preferences script.
