Subject: Reimplementado oekaki en Python y otros cambios

- Portados algoritmos de guardado de imagen a Python e incorporados en weabot
- Ahora los dibujos temporales se guardan en el directorio del board (adiós oek_temp)
- (Temporal) Los dibujos no se borran si no que se guardan como .bak
- Arreglado bug donde se pierde el dibujo si hubo cualquier problema al subir
