Moving the position of variables

[Thorlogy]

Is your feature request related to a problem? Please describe.
-Currently, the position of an initialised variable is fixed. It would be nice to be able to change the position of variables within the start block. This would bring more clarity.

Describe the solution you'd like

• Moving the variables could be done with a position number or by drag and drop.

Solved in blockly. Pull request can be found in Pull requests

Please test this fix in detail, there are a lot of changes that could (hopefully not) break the xml

I tested a lot. Everything looks fine except the following error:

• create a function with param p1 and p2
• use this in some function calls
• the generated target code is fine (first image)
• move p2 to the first position
• regenerate the target code (this includes a server round-trip)
• the sequence of parameters in blockly is updated correctly
• in the code generated the sequence is wrong (second image).
• btw: if you regenerate the target code a second time, everything is fine again. Strange :-<
