Add C# support

[shomykohai]

Describe the feature

Add C# support to the addon.

Reference: https://github.com/nathanhoad/godot_dialogue_manager/blob/main/addons/dialogue_manager/DialogueManager.cs

Why do you think it should be added?

C# support is surely something that many developers would benefit, allowing to integrate quest system with many codebases that already use it.
Many addons already support C#, such as DialogueManager by Nathan Hoad,

Hey :) A colleague and I are planning to start on this issue the coming days. Looking forward to contribute ^^

[shomykohai]

Hi, thanks, really appreciate it! Feel free to make a PR when finished!

[G0vinda]

Hey @shomykohai,
we wrote a C# implementation and wanted to create a separate branch for that, but it seems, that you need to give us permission to create a new branch :)

[shomykohai]

@G0vinda I can make a branch and you can target that branch with a PR directly!

[shomykohai]

Done! Try making a PR targeting it! It's called c-sharp

[shomykohai]

@G0vinda any news on the PR? 😄

[shomykohai]

@G0vinda haven't heard updates in a while, is the PR ready? 😄
I don't know if you already did it or I didn't see it 🤔 but I didn't receive anything in the pull requests. Maybe you uploaded the code in a fork of yours but didn't send a PR

Just want to be sure I'm not missing it 😄!

And thanks again for contributing!

@shomykohai sry for answering so late! We created a fork of your c-sharp branch, but didn't create a PR yet. The reason is that we wanted to secure our written code with Unit-Tests from GDUnit just like you did, but there seems to be an issue with GDUnit and C# right now. We get an error when importing GDUnit to a C# project at least. We will try to fix this and write the GDUnit creator if necessary. Afterwards we will continue with our PR including the unit Tests 🙏

[shomykohai]

Perfect! Thank you for the update! Will look forward for your PR then😄

Hey there!
Good news, there are new updates regarding C# and GDUnit:

godot-gdunit-labs/gdUnit4#680 (comment)

Hopefully soon it will be possible to continue on the PR! ⭐

[G0vinda]

Great! Thanks for the info! We will have a look :D

Update: this issue will need to follow #32 possibly.

It will be a matterof just moving some methods from a class to another.
I will document the changes correctly once I close the issue, and then I'll let you know how to handle some stuff!
