Support input type for pxtJsonOptions

[THEb0nny]

I want to create a property for the project, in which to implement the input type, so that the folder name can be used. So that when loading the project, the editor loads ev3 into the specified folder.

Right now the value can only be a checkbox. I ask you to review and correct any incorrect parts of the code.
