Implement a boolean/toggle setting that allows us to switch between using local and non-local dependencies.

Idea:
- Add a new dependency list called **localDependencies** to **NewKProjectModel**
- Add a boolean setting called **useLocal**
- If useLocal=true, then the project should use **localDependencies** over **dependencies**
- If useLocal=false, then the project should use **dependencies** over **localDependencies**

Use case:
- If I post the repo on github, I would have **useLocal** set to **false**, so it should use non-local (e.g maven/github) sources so that when people fork it, everything will work out-of-the-box.
- When I'm developing locally, I would switch to using local dependencies (**useLocal=true**). E.g: So that I would source from local dirs for XenoECS and ktruth for my own project so I could develop those libraries as well while developing the main project (XenoTactic)

Start at NewKProjectModel and trace how its dependency lists are consumed when resolving a project. Implement the requested localDependencies and useLocal behavior so each setting selects the corresponding source, then verify both true and false cases work for local development and forked repositories.
