Rewrite calls of meta_exec with new structure

Browse Source 
- Pass a table to meta_exec containing parameters, function to be
   called, scope string and requirements to check
 - Add basic ownership and contextid requirement checks in meta_exec
   when needed
 - Update README.md
 - Move assertion tools to assertions.lua

# Command tutorial
- help => Get help
- version => Get version
- open (x,y,z) _mode_ => Open the node to manipulate at pos (x,y,z) with mode _mode_ (default is 'fields')
- show => Show fields/path list at actual position
- enter _path_ => Enter next stratum through _path_
- leave => Leave current field and go back to previous stratum
- set _name_ _value_ => Set metadata _name_ to _value_ (create it if it doesn't exist)
- itemstack => Manipulate itemstacks in Node/inventory/\*/
- erase _name_ => Erase itemstack at field name
- write _name_ _itemstring_ [_count_] => Set itemstack in field _name_ with item _itemstring_ and count _count_. Default count is one, 0 not handled.
- list
- init _name_ _size_ => Create a list of size _size_ named _name_
- delete _name_ => Delete any list that could be called _name_
- close => Close node
- Soon to come, please refer to /meta help until then
