x3.0.0

Welcome to x3!
Not much changed since the last release, but now I have a shinier version number.

The few things that did change are as follows:

• Finished all documentation inside the documents/ folder
• Add the in, not in, and is type operators
• Implement xpp --show <module>
  • Loads and displays a module's .xconfig information
  • Available for both local pkgs/ and also dist-packages version
