Advanced block editor brush size not properly set after leaving and re-entering ships.

[CorvusCorax]

In the advanced block editor, the "brush size" can be setup from anything between 1x1x1 to 10x10x10 size in the top right corner. When the player leaves his ship with "R" and enters another one (or the same ship again), the previous brush size is still displayed in the selector, as it was last selected, but the brush size applied is always 1x1x1.

Ways to reproduce:
- Enter a ship
- Enter advanced editor (left CTRL)
- Set brush size to 5x5x5 blocks
- Place a 5x5x5 block for demonstration purposes
- leave the ship (R)
- re-enter the ship (R)
- enter advanced editor (left CTRL)
- Place a 5x5x5 block for demonstration purposes

Expected behaviour:
- The advanced build editor menu still displays 5x5x5
- Placing a block wiill place a 5x5x5 sized block of selected item

Actual behaviour
- The advanced build editor menu still displays 5x5x5
- Placing a block will only put a single block (1x1x1)
- Changing the block size in the menu has unexpected side effects, pressing the arrows behaves as if the value had been 1x1x1 even though it displayed 5x5x5 before
