Added mutation points. Currently they don't restrict much as you can simply exit and reenter editor to fill mutation points, but once we are ready we will limit editor to reproduction.

Working mutation points
Updated version number.
Split compound.* into multiple files by domain

By relocating according classes into compound_registry.*, compound_absorber_system.* and compound_emitter_system.*, issue #116 should be resolved.

- CompoundMovementSystem was kept in compound.*, because it is directly and only(*) linked to the CompoundComponent.
(*in relation to everything else that was located in compound.*)

Merge pull request #210 from HariboTer/207-Undo-redo-feature

Implemented undo/redo-feature for MicrobeEditor
A simple sliding-window 2D array datastructure, designed for cheap movement of the window of active elements.
Exposes the following to Lua:
 - constructor(width, height, resolution)
 - ::move(dx, dy)
 - ::get(x, y)
 - ::set(x, y, val)
Notes:
 - Currently not generic, but that should be easy once it's necessary
 - All x/y/dx/dy values are given in terms of the world coordinate space
 - Indexing locations outside of the current window area gives you the default value, and any input ot such a spot is ignored.

See #165
