allow portals to be lit with blocks (or in my case blue fire)

[kyrptonaught]

This is doable with CustomIgnitionSource.

Create a static instance of PortalIgnitionSource:

public final static PortalIgnitionSource BLUE_FIRE = PortalIgnitionSource.CustomSource(new Identifier("test","bluefire"));`

When registering your portal specify this as the ignition source:

CustomPortalBuilder.beginPortal()  
        .frameBlock(Blocks.DIAMOND_BLOCK)  
        .customIgnitionSource(BLUE_FIRE)  
        .destDimID(new Identifier("the_end"))  
        .tintColor(45,65,101)  
        .registerPortal();

Then you need to trigger the ignition when the block is placed. Add this to your Blue Fire block:

@Override
public void onBlockAdded(BlockState state, World world, BlockPos pos, BlockState oldState, boolean notify) {
    PortalPlacer.attemptPortalLight(world, pos, BLUE_FIRE);
 }

This doesn't work
