Configuration rewrite
= All references to Settings.Default have been removed and replaced by options.ini values
= Settings are configurable throug the Settings-Class. To add a new setting, create a new FIELD in the class and attribute it with  [CfgSetting(Section = "SectionName", Entry = "EntryName", DefaultValue = "DefValue")]
= Comments and Spacing in options.ini will be preserved
= Settings are exposed to Extensions, so they can add their own entries to options.ini. iRTVO internal-sections are proteced and read only.
* It's recommended to delete options.ini before first start of new version to get a clean options.ini

Scripting has been aligned to Extensions layout. Update of Demo-scripts in next commit
