[UI] Add instructive UI cues

[ribbybibby]

I think the consensus of the feedback we received on the LD site was that the game was 'confusing'. I think we could help this by adding small visual cues.

For instance:

• Add an arrow above the victory light that either persists for the whole level or disappears after a set amount of time
• Add an up-arrow or a jumping symbol above the BBW when his jumping ability is active, or perhaps his asset could 'glow' a bit?

• Add a 'theatre mask' symbol above the transformative light when a player is nearby, to communicate what it does?

Tomorrow I'm going to have a go at adding the code for these with placeholder assets.

I added UI to the transformative light in b9cd26f. It will show when either BBW or LRRH are within a certain distance of the pickup. We just need a theatre mask from the artist to put in the place of the placeholder cube I'm using at the mo.

Left to do:

• Add a glow to BBW when he is able to jump (I think this is better than an arrow)
• Add an arrow to the Victory point

I've added a glow to BBW in df61e60 which activates when LRRH is in contact with BBW.

We might want to look at finding a better asset for it but the code and objects are there in the editor. All it would take would be to swap out the material on it.

Left to do:

• Add an arrow to the Victory point

Will create the 2 assests tonight : Arrow and Theatre masks
Will you need different rotations of the arrow as seperate assests at all or is this something you can rotate in the code? (if you need to change the arrows direction)

[ribbybibby]

We can flip assets in the editor like we do with the wolf etc. So just the one arrow should do.

Sent Rob2 assests for the switcher and arrow

Added to build in 3aa2987. I implemented the switcher already. Stace and I already discussed that it's pretty small. But we can use this for now until we implement the camera panning stuffs and see if it still needs improvement. Closing this for now :)
