Refactor package structure and add web components.

Reorganized Kotlin package structure under 'nl.astraeus' and removed 'gradle.properties' file. Updated '.gitignore' to exclude 'gradle.properties'. Added new web functionalities including ID generation, websocket and HTTP request handling to support dynamic web content delivery. Adjusted server configuration and modified build version.
