The ARIA labels for the control panel movement buttons do not indicate direction when moving a block into or out of a loop

[sbates-idrc]

For example:

• "Move Step 3 forward 1 square into loop A"
• "Move Step 1 forward 1 square out of loop A"

For other cases, we include the direction, such as: "Move Step 2 turn left 45 degrees before step 1 forward 1 square"

What we want:

• "Move Step 3 forward 1 square into the beginning of loop A" [move right into]
• "Move Step 3 forward 1 square into the end of loop A" [move left into]
• "Move Step 1 forward 1 square out before loop A" [move left out of]
• "Move Step 1 forward 1 square out after loop A" [move right out of]
