Set local-lib to refer to the local import library #236

Instead of having the local import library object have no referent once the module is running except the words you bound from it, set the word local-lib in the module context to refer to it. This will let the developer control overrides, just like lib does globally. Also set local-lib to system/contexts/user in the script context. Even though there is nothing for scripts like the object target of local imports in modules, presetting the word will prevent it from being a problem when modules unnecessarily export it, and it will serve as a shortcut way to refer to the context, like lib. See http://issue.cc/r3/2116 for details.

Instead of having the local import library object have no referent once the module is running except the words you bound from it, set the word
local-libin the module context to refer to it. This will let the developer control overrides, just likelibdoes globally.Also set
local-libtosystem/contexts/userin the script context. Even though there is nothing for scripts like the object target of local imports in modules, presetting the word will prevent it from being a problem when modules unnecessarily export it, and it will serve as a shortcut way to refer to the context, likelib.See http://issue.cc/r3/2116 for details.
