LV2: Port another batch of plugins, EQ - SurgeTide

Some plugins won't compile for various reasons, these have been left out
for now. One plugin failed autoporting, so that one's left out too.

I have not tested these plugins yet, so no guarantees that they work, or
that they work right. Please report any problems or if there's missing
control info to the mailing list.
