Bug fixes

Polyscope GUI

• Fixed issues with no load program possibility, if the program contains a Set node configuration
• Fixed compilation error occurring in large program situations

URCAP API

• Fixed issue where an inserted Screwdriving node would have a non-default configuration with three Until nodes under it

Controller

• Fixed an issue that causes "No controller", typically associated with a heavy load, or stopping and (re)starting a program
• Fixed "No Controller" when multiple programs are sent in a short timeframe
• Fixed a bug where starting a primary program while Polyscope had another program loaded and running could cause the Polyscope to overwrite installation variables
• Fixed "No Controller" error that occurs after the protective stop when debugging a program using breakpoints
• Fixed "No Controller" issue happening due to a race condition caused by sending primary programs from more than one socket connection in a short timeframe
• Fixed issue where during interpreter mode the skip buffer method in some conditions can cause an "Unknown error: ValueStack::pop"
