This patch adds executil.BaseCommand, which contains some scaffolding for building generic and simple CLI commands. Also, executil.py contains a couple of predefined commands, such as Python, Shell, Powershell etc. fileexecutils, as well as userdatautils, were rewritten to use the new command framework instead, which greatly increases usability and simplifies cross platform issues.
