Broodmother is an actual boss

When I initially found the Broodmother for the first time in the exploration mode, it was insanely disappointing:

She looks like a scary bossfight waiting to happen, she's huge, at the end of a "dungeon", etc.

Yet I arrived ready for a brawl, only to kill her in 2 hits?

Well no longer! She now has over 10x more health, she spawns more units and I replaced her pebble throw attack (.. that's a weird attack to give the broodmother, even as a placeholder) with the poison dart attack.

She has really poor accuracy, she always aims too high, she'll only hit by mistake, so that's definitely something I'm looking into fixing!

So yea, to keep expectations low, this makes the broodmother go from overwhelmingly disappointing to moderately disappointing. her AI is still very much placeholder and my mod doesn't fix that (I'm looking into it, but I'm learning)
