This commits were reverted to exclude them from wesnoth 1.13.2 release because:
1) We are still unsure about the best name oftthese attributes
2) This breaks multiple campaigns, including LoW and the tutorial.
Feel free to revert this revert after 1.13.2 when thse issues can be solved..
previously there were 2 flags share_view=yes/no and share_maps=yes/no,
but only 3 possible settings (share both, share none, only share shroud)
(so share_maps= was ignored if share_viewv=yes). This made the wml code and
the c++ code needlessly complicated.
Now these 2 flags are replaced by share_vision=all/shroud/none
Instead of creating an enum, the MAKE_ENUM macro now creates a struct
which holds an enum and provides functions for enum <-> string
conversion.
This has multiple advantages:
1) We don't need MAKE_ENUM_STREAM_OPS anymore.
2) The generated struct is much easier to use in templates
3) We don't allow implicit to int conversions anymore.
4) The enum values are now declared inside the structs scope.
headers from lua/.. contain macros that can break other headers in
wesnoth, boost or other libraries.
In this case it was a macro
#define cast(t, exp) ((t)(exp))
defined in lua/llimits.h that broke a boost header.
