bug fix
Merge branch 'openmw-29' of https://github.com/zinnschlag/openmw.git into AIFix2
changed UniversalId::Type_Scene from index to string ID argument (argument is the worldspace)
added hint parameter for UniversalId viewing requests
changed edit requests from row index format to UniversalId/hint format
changed name of default worldspace (should reduce chance of a name conflict)
replaced global world->scene menu item with individual view context menu items in cell and reference tables
subclasses scene widget for worldspace scenes
add AIfollow to summoned creatures
fix
remove our stdint.h version that uses boost and force usage of system stdint.h
Terrain: support alternate coordinate systems. Get rid of LoadingListener for now
Terrain: remove hard dependency on shiny - can now be compiled without it (fixed function)
Render maps after *all* cells have finished loading

Still not fixing Bug #772, but at least this will allow for background loading of terrain.
Terrain: fix an embarrassing copy&paste mistake.
Terrain: moved ESM::Land load to earlier in the startup procedure

Required for background loading as we cannot load ESM::Land data from background threads.
Terrain: take cell world size into account for LOD selection
Terrain: geometry is now loaded in background threads.

TODO: background load layer textures and blendmaps.
"Distant land" setting has been removed for now (i.e. always enabled).
Include some more required Ogre headers explicitely.
Set StaticGeometry origin

Fixes an exception for coordinates far away from (0,0,0).
