Add an option in "Set Variable" to designate it as a PROJECT variable or a TASK variable

There is currently no way to programmatically create project or task variables. Only global variables or fleeting local variables that don't persist when the task ends. If you want something to be a task variable or project variable, you have to create it by hand within the gear menu for a task or project.

PLEASE add a "storage" option when setting a variable that allows us to designate a variable as a project or Task variable. This would enable the programmatic creation of these variables.
