Option for generating build command based on the project configuration

[Sipkab]

An option should be added that generates full command line invocation arguments for building the project based on the current configuration.

The option should be present in the saker.build menu for the project. Clicking on it should present a dialog that contains the generated command line that can be used to build the project.

The generated arguments should include all configuration for the project, including configuration contributed by extensions.

The dialog should allow (using a checkbox or something) to also include any curl or other (PowerShell Invoke-WebRequest) command the be prepended to it. E.g.

curl <saker.build> & java -jar <saker.build> <args>

Escaping of command line arguments should also be handled. There should be a Copy button that puts the displayed command to the clipboard.
