Rename BATTLETYPE_SHINY to BATTLETYPE_FORCESHINY (#1058)

* Rename BATTLETYPE_SHINY to BATTLETYPE_FORCED_SHINY

The name BATTLETYPE_SHINY gave the impression that it applied to all
battles with Shiny Pokémon, rather than merely battles with forced
Shiny Pokémon (i.e. Red Gyarados only).

* Rename to BATTLETYPE_FORCESHINY

Align name of BATTLETYPE with BATTLETYPE_FORCEITEM
