Make `brick`, `script`, etc a proper modules in python instead of objects

[DCNick3]

Making exported trik functionality to modules is more "in spirit" of python (this is how ghidra and IDA Pro integrated python into their projects, for example). Furthermore, it will allow one to set up code completion for trik objects in python IDEs by creating stub files for those modules. There is no such a possibility with trik APIs being objects in the global namespace.

I propose to put trik-specific functionality into trik module, as a further improvement of code structure. Also, one would be able to write from trik import * to introduce all those modules into a global scope (even though it's not recommended by python community, as it reduces code maintainability).
