* m1 + shift drag: snapped modes of manipulators:
freedrag: constrain to axis with biggest move amount
rotate axis: snap to angles, multiple of 15'
scale axis: scale all axes synchronously
scale free: scale axes with non zero drag synchronously (i.e. two visible ones in projection views)
misc...
* fix: CameraFreeMoveUp, CameraFreeMoveDown shortcuts are editable
* prism, cone prefabs: increased precision
* fix: out of pivot rotating is active from start, no additional magic is needed for that
* fix: could lock (but not set) transform origin in non-pivoted mode
* arbitrary rotation dialog allows decimals
* fix: grid rendering with ToggleGridSnap off
* fix of: scale tool scale, locked to 1 for things w/o bbox with bigger grid (e.g. single misc_model)
(snapped drag start was = 0, scale func depends on initial click point: closer to center = more extreme scaling)
* fix: make detail / structural are undoable
* default autosave period: 5 -> 15 minutes
* texBro option: hide nonShaders in common folder; def = yes; are shown, if are in use
