Add a usable shower model + a bath tile texture
Relates to #29
The world of OLives just got a bit bigger again. The shower object, while technically existing before with a dummy model, will be used soon hopefully as the first object that requires another to enter it to perform a job (i.e. take a shower).
If that mechanic works properly, that opens up a world of new possibilities – the next work will be finishing this up though and potentially looking into some stability issues when updating the UI, a known issue. :\ Anyway, check out this amazingly detailed new model and texture. Lifelike.
