Named arguments support in IDE

[Frizi]

Pull Request Description

Added support for named arguments in IDE.

named-arg.mp4

Named arguments are now recognized in node expressions. The function argument placeholders are rendered around series of named arguments. Insertion and deletion of arguments either by connection dragging or by widget selection will cause arguments around to be rewritten into appropriate form, such that the meaning of the expression doesn't change. We no longer need to introduce any wildcards (_) in argument positions when editing an argument list of a resolved method.

For unresolved function calls, the old behaviour remains, as we don't have data about argument names or their desired order.

The code is easy to read, has beautiful comments with explanations and I do not have any comments to the code really. Needs QA, but beside that, it's very nice!

QA report

I noticed two issues that may or may not be regressions.

Colors of edges seem to be random

Notice the color of the this argument changes when I connect one of the inputs.

Clicking on the output port creates an edge

I connected the first edge, then I clicked on another node's output port – and you can see what happened on the video. After that, clicking on output ports and dragging edges produces weird results without much pattern. Sometimes I even couldn't drop the connection without connecting it to anything. It happens even after reopening the project.

@vitvakatu amazing job with finding the issues!

[Frizi]

@vitvakatu I have reproduced both of those issues on current develop. Those are not introduced in this PR.

port-click-edge-bug.mp4

The reproduction indeed seems a bit random. The edge coloring bug is fairly easy to trigger. The one when clicks cause edges to be modified or added required some more fiddling. I randomly connected and moved things around. After a while, clicking on ports started causing weird behaviours.

QA accepted. The spotted regressions will be reported as issues by me.
