CodeBlocks 2

- Function and branch blocks add markers in the ground showing direction of the branch / function

- When robot stops / bumps into a wall - user receives a message

- When robot tries to build, but does not have item - it pauses the execution and sends message to the player

- Reworked commands /cb /cbf /cbr /cbb and /cbb all . Also pressing C will open CB main menu.

- When using a base block for a set of blocks, GUI will not listen to key presses - Each item in the drop down box has a number, pressing that number will close the gui and set block to matching item in the drop down

- Debug works a bit differently. When turning it on - user will be asked to place a Function Block where the debug base will be set instead of instantly setting it at player's current location.

- Fixed some minor bugs
