TEKELI-LI! TEKELI-LI!!!!!

Added shoggoths. They speak using the migo_speech.json file. changed the way that works. (Now you can add monster specific lines). They absorb objects they walk over. Which gives them bonus HP. They hit HARD, are hard to kill etc. Pretty dangerous. But slow.

Updated the DEVELOPER_FAQ.md a bit.
Fixed small speech error.
fixed tabs.
Updated the absorbtion string as suggested by Adrian219
