2021.8.8

Thank @inkydragon (woclass) for the PyInstaller infrastructure! Now we can ship Zeno on both windows and linux with less ad-hoc effort :)
To run, simply download and extract the zip, and run ./launcher on linux, launcher.exe on windows.
On the other hand, this release still doesn't contains OpenVDB for windows :( And GPUMPM related stuff is not included on both windows and linux as well.. I'll try to figure out how, thank for your support! Also notice that due to the difference of PyInstaller (it doesn't ship libc.so), it will likely fail to work on Ubuntu 18.04 and CentOS 7 due to their low glibc version..
Anyway, here's the updates: arts has now moved to graphs, ZFXv2 being supported for easy wrangling, viewport now being horizontally splitted, timeline now click-to-stop, nodes support dynamic ui like MakeDict, MakeHeatmap... etc., have fun!
