Support LuaJIT cdata and ctype values in Inspector:putValue().

Browse Source 
Add special handling for cdata and ctype types provided by LuaJIT: use
tostring() to print values of those types, which either provides a more
meaningful default type description (e.g. 'ctype<uint64_t>' instead of
'<ctype 1>') or a user-defined value as described at
http://luajit.org/ext_ffi_api.html#tostring
