Ev3sim

Fixes an issue with the bot editor

EV3Sim should now prompt you to update automatically, hopefully saving some time having to check for new installers.
Also fixes an issue I introduced recently with custom tasks not loading.

This doesn't come with ev3dev2. Will fix the installers tonight.

Big changes today:

* Workspaces are no longer required for EV3Sim to function.
* Bugs are more likely to be correctly recorded in `error_log.txt` in ev3sim's install location.
* The windows installation now comes with an exposed version of Python that VSCode can recognise. This allows you to execute python programs outside of ev3sim, as well as install packages, and use this installation for linting purposes.
* Support for `reflected_light_intensity` and `color` prediction on colour sensors.
* Minor Bug Fixes.

This release adds mindstorms support! Big thanks to angustrau and Dalordish for their work on mindpile. Initial support is minor, some larger changes on the way :)

Also a few minor fixes such as downloading custom tasks over the school network.

Fixes a bug which would cause ev3sim to crash instantly if no workspace folder existed.
