- Run task tab no longer automatically starts uploading framework on connecting to a board without framework installed, instead the user is prompted to load the framework using the config dialog.

- Config dialog now prompts users to disable the USB flash drive before loading the framework if they try and load the framework on a board with the flashdrive enabled.  Implemented because disabling the USB flashdrive greatly reduces occurence of pyboard filesystem corruption.
