Stai update to Chia 1.2.11 & New GUI design

This release includes all the security and performance improvements of Chia's 1.2.11 update.
Features included :
Blockchain name changed from Staicoin to Stai
New GUI design ! (only dark mode available for now)
Protect your Stai wallet with a passphrase !
Madmax plotter directly added to the GUI (when you create a plot it uses the madmax script)

IMPORTANT
Due to the change of blockchain name once you install this version it will create a new folder named .stai and you will have to enter your mnemonic back again. To quickly add your plots back, you can copy the plot_directory section with all the paths from the old config.yaml to the new one !
Please do not re-use the same config.yaml as previously, instead edit the new one to avoid any compatibility issues.
Please also copy your blockchain database (/db & /wallet folder) from . staicoin to .stai to avoid starting over the syncing process !

Download links removed, please refer to 1.1.1 release for now thank you !
