Minor update v4.8: UI and parameter window improvements

Added

• gui/simulation view: borderless rendering (world is rendered periodically) + parameter to (de)activate
• gui/simulation view: adaptive space grid for orientation + parameter to (de)activate
• gui/simulation view: new coloring which highlights particular cell functions
• gui/simulation parameters: addon widget introduced
• gui/simulation parameters: center button in spatial control
• engine, gui/simulation parameters: attacker and particle absorption depending on genome complexity
• engine, gui/simulation parameters: addon for genome complexity measurement
• engine, gui/simulation parameters: low and high velocity penalty for energy particle absorption

Changed

• gui/simulation parameters: move expert settings for absorption, attacker, external energy and color transition to addons
• gui/simulation view: short white background flash after creating and loading snapshots (now called flashbacks)
• gui/simulation view: cross cursor in edit mode
• gui/simulation view: mutation coloring adapted such that color changes occur only after major structural mutations
• gui/statistics: adapt plot heights depending on the visible data points
• engine: memory consumption reduced (~ 10% depending on the data)
• server: support for large simulation files (up to 144 MB)

Fixed

• gui/simulation parameters: show base tab when new simulation is loaded
• gui/statistics: maintain previous statistics data after resizing the simulation
• engine: fixed rare and spontaneous crashes that occur when many cells and connections are destroyed
• engine: new completeness check counting the actual cells of the creature against the cells in the genome
• engine: wrong displacement calculation in case of zooming and moving objects fixed
