v0.22 performance

Rustylife uses u32 nodeid/arena entries with u64 coordinates. It has an aggressive garbage collection algorithm. This is done so it does not overflow u32 nodeids. It also reuses garbage collected nodeids asap, never allocating new nodeids when there are reusable nodeids available. Looking at the code this presented an optimization opportunity. The nodes hash was removed. This improves performance vs v0.21 by ~25%.

game_of_life - is a Linux executable
game_of_life.exe - is for Windows and was tested using wine

Run an executable and connect via a browser to http://localhost:7654/ and have fun. You can use the Edit button, then Cntrl+C to copy a pattern, and Cntrl+V to paste it into rustylife's edit dialog, then press Paste put the pattern onto the board. Use Play to run - it goes for about 126 million generations. Speed and Step control how fast it runs. Left click centers the board - you can also drag using the left mouse button. The mouse wheel zooms as does moving up or down holding both mouse buttons.
