UI improvement: Mark functions in extension with an icon

[Wend1go]

Description

When working on a larger external extension it gets hard to find the function you are looking for in the list.
There should be a visual way to distinguish between conditions, actions and expressions.

Solution suggested

Mockup:

Describe the solution
Adding an icon in front of each function name makes it easy to see if we are dealing with a condition, action or expression.

Alternatives considered

One could choose a name prefix for functions like "actionDoThis" / "aDoThis" or "condition_IsThis" / "cIsThis" but since the function names are also later visible in the event sheet when they get used this would make the events harder to read.

Totally, that's an easy win to have an icon. Also a good opportunity to add a "lock" or something like this to show private functions/methods.
