Global variables set by one plugin can be overwritten by a second plugin

With currently implemented solution, different plugins can overwrite previously set variables with the same name. There is no validation, if global variable with specified name already exists. It can lead to plugins' malfunctioning. Maybe we should implement some kind of validation or make strict naming convention for globals set in plugins?

what needs to be done if global variable with specified name already exists?

[walterbender]

We should perhaps manage this by convention: a three-letter prefix for each plugin used for its globals and internal block names (which also can collide).

Can't we namespace them internally?

[walterbender]

probably, yes.

I'll look into this issue and see if I can I fix it.
