Minor update v4.9: External energy extensions

This update extends the possibilities for using an external energy source. It allows you to control the inflow and backflow of energy from/to an external source. It even offers the possibility to perform simulations without energy particles but with limited cell lifetime. Exciting examples can be found in the simulation browser under Primordial Ocean. Furthermore, a real-time counter was added (it is saved with the simulation settings and reset appropriately when a snapshot is restored), the rendering of the cells was made a bit nicer for high zoom levels, and a new coloring mode was added, which not only visualize the mutation but also the cell functions.

Added

• engine, gui/simulation parameters: conditional and unconditional energy inflow from external energy source
• engine, gui/simulation parameters: energy backflow to the external energy source
• gui/simulation view: combined mutation and cell function coloring
• gui/temporal control window: real-time counter

Changed

• gui/simulation view: cells are rendered smoother
• engine, gui/simulation parameters: external energy becomes a scalar value (no color dependence)

Deleted

• engine, gui/simulation parameters: energy pump from constructors (substituted by conditional energy inflow)

Fixed

• serialization: activation of necessary add-ons for old simulation parameter files fixed
• gui/browser: preserve subfolders when renaming folders
