#38 block_motor_done causes error with simulator

[biolizard89]

Steps to Reproduce:
1. Enter the following code in IC:

void main()
{
move_relative_position(0, 1000, 1100L);
block_motor_done(0);
}

2. Save it as "test1.ic".
3. Click "Simulate".

Expected Results:
IC should load the simulator without errors, since the
file compiles fine with the Check button.

Observed Results:
IC gives the following error message:
"test1.ic(line 5): Error: SIMLIB ERROR - Function
block_motor_done undefined"
