[Ann] TelePharo is updated for new Calypso version

Hi.

I finally tested and fixed TelePharo based on new Calypso version 0.8. So all new features of Calypso are available for remote images.

It is new stable version v0.2.x. 

For slow remote servers it is good to disable "expensive" plugins. 

For example overriding method icons (up/down arrows) decrease browser performance on Raspberry. 

For such cases prepare remote images with extra script:

ClySystemEnvironmentPlugin disableSlowPlugins.

It disables most heavy features including critiques plugin and covered methods decoration (test icon over domain methods).

You can also disable it from command line: 

./pharo PharoServer.image remotePharo --startServerOnPort=40423 --disableSlowPlugins

Best regards,

Denis
