Refactoring after update, new connector GUI features, #551 fix, optimisation patch

Refactoring after update

Now in GUI you can see connected block for each direction (also info about block when hovered)
Connector name is now correctly displayed when reconnecting for other players as well
Directional name toggle buttons now do not lose state after reopening the interface.
Not connected direction always disabled
Direction connected to other connectors and cables is always active New GUI Example:

№	Description	Before	After	Channels
1	Combining simulation and real insertion methods	Doing work twice, simulate then real	Unified method based on pipez one. Still safe but faster	Item channel Fluid channel
2	Cache connector position	Request position every tick for every connector	Stored as new field in cached connectors	All channels
3	Skip processing of full inventories if there are many extractors	Trying to insert to full inventory for every extractor in cycle	If we have more than 2 extractors, we memorize the full inventory and skip it for the next one. We perform this operation when processing the first and middle extractor	Item channel
4	Cache rate for energy channel	Check limit rate every tick for every connector	Stored as new field in cached connectors	Energy channel
5	Check required energy	Iterate over all extractors	Stop the iteration if we have obtained enough energy to fill all consumers	Energy channel
